  • Help identify the pattern for reacting on updates

    - by Mike
    There's an entity that gets updated from external sources. Update events are at random intervals. And the entity has to be processed once updated. Multiple updates may be multiplexed. In other words there's a need for the most current state of entity to be processed. There's a point of no-return during processing where the current state (and the state is consistent i.e. no partial update is made) of entity is saved somewhere else and processing goes on independently of any arriving updates. Every consequent set of updates has to trigger processing i.e. system should not forget about updates. And for each entity there should be no more than one running processing (before the point of no-return) i.e. the entity state should not be processed more than once. So what I'm looking for is a pattern to cancel current processing before the point of no return or abandon processing results if an update arrives. The main challenge is to minimize race conditions and maintain integrity. The entity sits mainly in database with some files on disk. And the system is in .NET with web-services and message queues. What comes to my mind is a database queue-like table. An arriving update inserts row in that table and the processing is launched. The processing gathers necessary data before the point of no-return and once it reaches this barrier it looks into the queue table and checks whether there're more recent updates for the entity. If there are new updates the processing simply shuts down and its data is discarded. Otherwise the processing data is persisted and it goes beyond the point of no-return. Though it looks like a solution to me it is not quite elegant and I believe this scenario may be supported by some sort of middleware. If I would use message queues for this then there's a need to access the queue API in the point of no-return to check for the existence of new messages. And this approach also lacks elegance. Is there a name for this pattern and an existing solution?

  • Complete Beginner to Game Programming and Unreal Engine 4, Looking For Advice [on hold]

    - by onemic
    I am currently a 2nd year programming student(Just finished my first year so I will be starting my second year in September) and have mainly learned C and C++ in my classes. In terms of what I know of C++, I know about general inheritance, polymorphism, overloading operators, iterators, a little bit about templates(only class and function templates) etc. but not of the more advanced topics like linked lists and other sequential containers(containers in general I guess), enumerations, most of the standard library(other than like strings and vectors), and probably a bunch of other stuff I dont even know about yet. I subscribed to Unreal Engine 4 as I was very intrigued by their Unreal Tournament announcement earlier this month, especially after hearing that UE4 is going completely C++. Of course my end goal in doing this programming program is to eventually go into game/graphics programming. Since it's my summer off, I thought what better way then to actually apply some of my skills to a personal project so I actually have a firmer understanding of C++ past what my professors tell me. My questions are this: What would be the best way to start off making a small personal game in UE4 as a project for the summer? What should I be aiming for, especially for someone that is still learning C++? Should I focus on making a simple 2D game rather than a 3D one to get started? Seeing the Flappy Chicken showcase intrigued me because before I thought the UE engine was pretty much pigeonholed into being for FPS games What should my expectations be going into UE4 and a game engine for the first time?(UE4 will be my first foray into making a game) What can I expect to gain from making things in UE4, in terms of making games and in terms of further fleshing out my knowledge of C++? Would you recommend I start off 100% using C++ for scripting or using the visual blueprints? Since I'm not a designer, how would I be able to add objects and designs to my game? For someone at my level is retaining the UE4 subscription worth it or is it better to cancel and resub when I learn enough about UE4 and C++? Lastly is there anything to be gained in terms of knowledge/insight through me looking at the source code for UE4? I opened it in VS2013, but noticed that most of the files were C# files and not cpp's. Thanks in advance for taking the time to answer.

  • HD Tune warning for "Reallocated Event Count" with a new/unused drive. How serious is that?

    - by Developer Art
    I've just looked at the health status of my old 2,5 inch 500 Gb Fujitsu drive with a popular "HD Tune" utility. It shows a warning for the "Reallocated Event Count" property. How serious is that? The thing is that the drive is practically new. I pulled it out of a new laptop over a year ago and never used it since. Right now it only has 53 "Power On" hours which sounds about right since I only had it running a few evenings overnight before switching it for something more performant. Does this warning indicate that the drive is likely to fail some time in the future? I'm somewhat perplexed since the drive is effectively unused. What is more, I have arranged with somebody to buy off this drive since I don't really need. It is 12,5 mm thick (with 3 plates) meaning it doesn't fit into an external enclosure which makes it quite useless to me. Can I give away the drive without having it on my conscience or better cancel the deal? In other words, can the drive be used safely for years to come or better throw it away? I'm running a sector test now to see if there are any real problems. Will post the results as soon as they're available.

  • Windows Server 2003 Trial Activation Issue

    - by Adam Batkin
    I have a Windows Server 2003 (R2 Enterprise with SP2) VM, originally installed with a trial license. We forgot about the server, and now more than 120 days has passed, and I can't do anything with the server. I seem to be at a dead end with the existing installation. When I log in, I get: The evaluation period for this copy of Windows has ended. Windows cannot start. To continue using Windows, please purchase and install a retail copy of the product. Fine. I'll do that with my MSDN media. I should add that safe mode works, but there isn't anything obvious that I found to help me there Next up, I tried repairing my installation: Boot from Server 2003 R2 Enterprise with SP2 media, tell it I want to install (as opposed to recovery console), then let it repair the existing install. Once that completes and reboots I log in: This copy of Windows must be activated with Microsoft before you can continue. You cannot log on until you activate Windows. Do you want to activate Windows now? To shut down the computer, click Cancel. Great! I click "Yes" and am left with a big blue screen. Not a blue screen of death, just a blue screen (i.e. the default windows desktop background color). No Ctrl+Alt+Del. All I can do is power cycle. I have some complex third-party software on there that I can't reinstall, which is why I haven't already built a fresh Windows VM and copied everything over. I have a backup of the VM from after trial period expired but before I installed anything. Ideas?

  • MultiView 2000 terminal emulator not printing correctly to Generic/Text Printer on Windows 7

    - by FantaFan
    Guys & gals, Hope someone can shed some light on this. I am downloading reports from an AIX-based system by directing them to a TT printer which the terminal emulator (MultiView 2000) intercepts and directs to the default printer on the local system. This local printer is configured as a vanilla Generic/Text printer attached to a FILE port. When I print from AIX, the output is spooled down and the local printer prompts for a file name into which to save the file...but not under Windows 7. This has worked fine for many years, on both Win2K and WinXP. However, on Windows 7 the output gets spooled as a file into spool\PRINTERS (and looks as expected) but the print job then hangs with a status of "Error - Printing" and never prompts for a file name. I have to cancel the job. The Generic/Text printer works as expected with other applications. I have tried setting the printer to print directly rather than spooling but this only serves to hang the terminal session too. I've also tried to run the emulator in Windows 2000 Compatibility Mode and as Administrator in case it was something like that but with no luck. As you might expect, it does work fine in XP Mode (as long as I print to a printer defined therein and not the host's printer) but operationally this isn't going to be an option. Obviously this emulation software is a decade old (at least) and I could just cross/upgrade all the users (at a cost) but, before I do so, has anyone seen this sort of behaviour before and found some sort of fix? Remote OS: AIX 5 Client OS: Windows 7 Pro (32-bit) Printer: Generic/Text on a FILE port TE Software: MultiView 2000 (320-bit) Thanks in advance.

  • Windows Backup failed as another backup or recovery is in progress.

    - by remunda
    Hi, i have set up backup schedule on our server. SQL Server 2008 to 01:00am on windows server 2008 R2 to 4:00am. Sql backup runs well, but system backup ends sometimes with error. The error is : http://technet.microsoft.com/en-us/library/dd364768%28WS.10%29.aspx I mean, that is caused by SQL Server, because it unexpectedly runs backup. this is from sql server log (it runs for every database): Date 4.2.2010 4:00:21 Log SQL Server (Current - 29.1.2010 23:25:00) Source spid72 Message I/O is frozen on database master. No user action is required. However, if I/O is not resumed promptly, you could cancel the backup. and Date 4.2.2010 4:00:24 Log SQL Server (Current - 29.1.2010 23:25:00) Source Backup Message Database backed up. Database: master, creation date(time): 2010/01/29(23:25:32), pages dumped: 370, first LSN: 859:56:37, last LSN: 859:80:1, number of dump devices: 1, device information: (FILE=1, TYPE=VIRTUAL_DEVICE: {'{17B91D5C-9968-4D11-A7F1-1A31523D32F0}25'}). This is an informational message only. No user action is required. My questions is: Why runs sql backup with windows backup? How can i dissolve this that errors? Thank you a lot.

  • Ideal Bacula appliance?

    - by Ricket
    I'm an intern at a small company and we (the IT department of two) manage <100 client computers and a handful of servers. Currently we're using a company's appliance to handle backup; it does a small backup every night and a full backup every weekend, and a guy comes on Wednesday to take an offsite backup drive (and gives back last week's drive to swap with it). Lately this system, mainly the appliance, has been having problems, so we are looking for an alternative. I'm researching other companies but also looking into what we might expect from trying to do this ourselves. There will undoubtedly be a large learning curve, but hey, that's what serverfault is for, right? :) So anyway I was looking at Bacula. Feature list sounds great, documentation is plentiful, but it's only software. So my question is, what is the ideal backup server to run the Bacula server software on? And not only the server but other related appliances. Our current backup appliance uses only hard drives, not tape drives. It has several plugged into it at one time, in hotswap bays on the front of the machine. I couldn't help but notice though, it's hardly more than Windows XP with hard drive bays, a PCI eSATA card (which connects to another appliance extension piece with 2 more bays), and their software. Since the company will take back their appliance if/when we cancel with them, where can I go to configure a server with these kinds of things? Maybe I'm being naive, I'm sure Dell (and any other computer company) sells them in the small business section of their website, but I wanted to make sure that there's not some other more recommended place that other companies are getting their hardware from, and that I don't need anything special for Bacula.

  • Toshiba Portege M400 screen rotation not working under Windows 7 x64

    - by Christi
    I have installed Windows 7 on my Toshiba Portege M400. This in itself was relatively tricky.* However, the button utilities aren't quite working for me. One of the buttons tries to launch the Toshiba Assist program, which doesn't appear to be available under Windows 7 for the M400, but this I can live without. More important is that the screen won't rotate as it is supposed to when you hold the "cancel" (X in a circle) button on the bezel. The PC is set to run "C:\Program Files (x860\Toshiba\Toshiba Rotation Utility\phtrot.exe". There is a "trot.exe" file in the same directory (the former appears to be to cause slightly different behaviour when rotation is done by press and hold). Neither of these programs rotates the screen either by using the buttons or from the command line. The screen is rotating normally when switching from tablet to laptop mode, so there does not appear to be an inherent problem with rotation. I'd just like to be able to use the buttons on the side of the screen to change the screen orientation. Windows XP used to have a "setrot" utility to do this, but that seems to have gone in Windows 7 Thanks for your help. *Just in case anyone comes looking for how to do this, you need to extract driver files from http://cdgenp01.csd.toshiba.com/content/support/downloads/util_raid_os2007252a.exe, which does not seem to be listed among the available files for the m400. This executable contains the SATA interface drivers that will need to be loaded by the installer before it can see your hard disk drive. It needs to be unpacked and the files copied to a USB key which they can then be loaded from in the install process. The utilities etc. for installation post windows install are all available from the Toshiba USA support website.

  • SQL Server 2005 Express: upgrading to SP3 in mixed-mode installations

    - by Jeroen Pluimers
    I'm having trouble upgrading SQL Server 2005 Express SP1 to SP3. The SP1 install uses mixed mode authentication (so there is an sa password). This is the message I get: TITLE: Microsoft SQL Server Setup ------------------------------ None of the selected features can be installed or upgraded. Setup cannot proceed since no effective change is being made to the machine. To continue, click Back and then select features to install. To exit SQL Server Setup, click Cancel. For help, click: http://go.microsoft.com/fwlink?LinkID=20476&ProdName=Microsoft+SQL+Server&ProdVer=9.00.4035.00&EvtSrc=setup.rll&EvtID=SQLSetup90&EvtType=28108 ------------------------------ BUTTONS: OK ------------------------------ The link then tells me To continue you must provide a strong sa password. I tried some searching, and found something about BPAClient.dll, but this batch-file does not fix it: mkdir "%ProgramFiles%\Microsoft SQL Server\90\Setup Bootstrap\BPA\BPAClient" copy "%ProgramFiles%\Microsoft SQL Server\90\Setup Bootstrap\BPA\bin\BPAClient.dll" "%ProgramFiles%\Microsoft SQL Server\90\Setup Bootstrap\BPA\BPAClient\" So I think the clue is the strong in the link above. Am I on the right track? Where do I find more information on the strongness of an sa password? --jeroen (who will adjust the question when he has dug further)

  • Upgrading Visio 2000 to Visio 2007

    - by dirtside
    I have Microsoft Visio 2000 SR 1, and recently purchased Microsoft Office Visio Standard 2007 with the understanding (supported by the product info and some other research) that I'd be able to upgrade. However, when I install 2007, it tells me it can't find a previous install of Visio, but... it's right there! Here's the exact message: "Setup can't find a version of Microsoft Office on your computer. If Office is installed on a disk or network share, click the browse button to select the appropriate disk or share... (etc.)" No matter which directory or drive I pick (various Office installs, the old Visio install, various subdirectories) it gives the following message: "The path you have chosen does not point at a qualifying upgradeable product. Click 'Retry' to try again or 'Cancel' to quit setup." Any ideas? This is a legit copy of Visio 2007 (purchased from Amazon) and the copy of Visio 2000 is legit as well. I'm not sure what exactly the installer is looking for that it would consider a "qualifying upgradeable product". A specific file?

  • Print jobs sent to server OK, but then get deleted

    - by Paul Morrison
    I have 2 HP computers, one running Win XP SP3, one running Win7. I have a Lexmark X4270 All-in-One printer attached to the Win7 machine via a USB port. I can print OK from the Win 7 machine, but when I print from the WinXP machine, the print job shows up in both print queues (showing the same number of bytes - which is good!), but then the status gets changed to "Deleting - Sent to printer", and that status shows up in both print queues. The print job then stays there until I do a cancel, followed by a system restart. FWIW the owner is shown as Guest, but I have permission for Everyone set to print... I believe I have up-to-date drivers; I don't believe it's a firewall problem. What I would like to see is the Win7 machine's reason for deleting my print jobs - is there a diagnostic tool available? Also, I notice that the port for this printer on the WinXP machine is set to USB001 - I would have thought something like \servername\sharedprinter would be more appropriate - and I can see that in the list of ports, but the system doesn't let me change the port name from USB001... Could someone shed some light? I have spent hours on this! TIA BTW I can do file sharing, no problem!

  • MS SQL Server 2005 Express rebuild master DB problem

    - by PaN1C_Showt1Me
    Hi ! There has been a power loss on our server and i cannot start the SQL service because the master DB is corrupted (as the log states). I found many articles recommending running the setup.exe with optional parameters: This is what I did: I've downloaded SQLEXPR32.EXE from MS page and ran it The first problem was, that it extracted all the setup files and started the default installation procedure. (which was unuseful for me as I need those params). If I canceled it, all the extracted files disappeared. That's why I decided to copy the extracted files somewhere and than cancel the default installation. Now I'm trying to run the setup.exe from the extraction: setup.exe /qb INSTANCENAME=MSSQLSERVER REINSTALL=SQL_Engine REBUILDDATABASE=1 SAPWD=xxxxx it asks me if I want to rewrite the system db, which is what I need, but then while installing I get this error: *An installation package for the product Microsoft SQL Server 2005 Express Edition cannot be found. Try the installation again using a valid copy of the installation package 'SqlRun_SQL.msi'* Then it tries to install something and it states: cannot install because the same instance name already exists. But I don't want to install a new instance .. Any idea how to solve this, please? Thank you in advance !

  • Windows Vista: Screen remains darkened for 30-60 seconds *after* UAC prompt

    - by sf2k
    Fixing someone's Vista computer. Process: I click any program or process that opens a User Account Control prompt. Screen goes dim so you may hit Continue to perform a secure user action. I click Continue Screen goes black for 30 seconds to 1 minute while you wait for the screen to return. In another example I click Cancel and screen still then goes black for 30 seconds to a minute. In that timeframe a chime goes off while you wait. (No chime if it was being cancelled.) Then screen comes back to continue with whatever. Something is occurring after the UAC prompt. Considering everything is practically a UAC acceptance this can get pretty annoying pretty quickly. Laptop has external monitor to regular external plug. Works fine. Laptop also has USB IOGEAR additional external video card. This is problematic but when unplugged same above behaviour occurs. I've ruled out monitor interference since same blackout after the UAC prompt appears with external monitors plugged in or when rebooted with no external monitors. Any suggestions on how to address this problem?

  • Microsoft Office 2003 applications crash on 'Save As' to a network mapped drive

    - by Archit Baweja
    Hey guys, so I'm not sure if it belongs on ServerFault forums so figured I'd ask here first because its a workstation/client side issue. I have a client where we have windows server 2003 setup, with windows xp professional setup on all the workstations. We've setup a 'domain' and all workstations logon to the domain (authenticated by the Windows Domain Controller), and in the logon script we map drives on to each workstation. Everything is working peachy except for one workstation, where when I open a file in excel from a mapped drive, it opens fine, but when I go to hit Save As, the Save As dialog pops and hangs up. I cannot perform any other action in excel. When I try cancel the Save As dialog, excel crashes. The mapped drive opens up fine in Windows Explorer. To further investigate this issue, I created a new blank text document on the network drive in Windows Explorer. I then opened it. Then hit save as, and the Save As dialog opened up fine and it would let me save the document. I repeated the above steps for a word document. However this time the Save As dialog hung/froze again. So I'd imagine its a Microsoft Office Issue. Any ideas?

  • CD-ROM Cant Be Accessed After Installing VMware Tools on VMware Server 2.0.2

    - by Optimal Solutions
    Using VMware Server 2.02, I set up a new VM (Windows XP Pro) applied all of the updates, added Windows addons from the install CD, etc... I got it to a stable point and up through that point I was able to access the CD-ROM drive (E: on my host). What I never did before was install "VMware Tools" and since it claims to give better mouse and video support, I gave it a shot. What it does is it places the install package in a virtual CD-ROM drive. I ran the install, no errors and it wants a reboot. I log back in after reboot and pop in the install CD for Microsoft Office 2003 and I receive the message "Please Insert A Disc Into Drive D:". Drive D: would be the next logical drive after the C: drive where I chose to install the OS. The message box sits there and if I click "Cancel", to return to Windows Explorer, the status bar seems to blink ever 1/2 second - as if its polling for a CD-ROM drive or something. No bangs or exclamations in the Device Manager for any hardware. I had taken a snapshot prior to the VMware Tools install and upon restoring it, the CD-ROM is back. I made copies of two other VMs, installed the VMware Tools on those VMs and both experienced the same issues: Windows 2003 Server and Windows 7 (32-bit). Has anyone seen this issue and know of a fix for this? It would be nice to have the better graphics and better mouse control AND use my CD-ROM drive as well! Thank you.

  • .htaccess authorization requiring username/password for every resource

    - by webworm
    I am using Apache2 on Ubuntu and I have having some "weird" user authorization issues. I am using .htaccess to control access to my directories. I have many users and have grouped them into user groups which are defined in a "group" file. I then use .htaccess within each directory to define which users have access to the directory and which do not. Here is an example .htaccess file. AuthUserFile /var/local/.htpasswd AuthGroupFile /var/local/groups AuthName "Username and Password Required" AuthType Basic require group design admin Everything is working with one exception. I added a new user to one of my groups and though they can gain access to the directory they are prompted for a username and password for every resource (i.e. image, CSS). After a while I can just keep selecting "cancel" and I will get a page with just html with no images or CSS. I would think the browser would just cache the username/password. It seems to be working well for other users. Any thoughts?

  • How do I stop mail.app and its nag screen from opening upon login in OS X if I don't use it

    - by user26453
    Currently whenever I start OS X (10.6.2), mail.app starts up with a "Welcome to Mail" dialog, asking me to create an account by inputting name, email address, and password. If I cancel this dialog, the app just hangs and I have to force quit it. I do not use the mail.app and I do not want it to start up with OS X. I have checked the login items and it is NOT present in the login items list for my account. I have also ctrl+clicked the doc icon that appears and confirmed there is no option enabled for "Run at Login". If I go ahead and just spam continue through the dialogs for a new account, I can get through to actually using Mail and accessing preferences. I cannot find a startup option in Mail preferences. After I have completed this, if I now restart, Mail does NOT open automatically. However as soon as I delete the account that I created, it once again goes back to popping up a "Welcome to Mail" dialog every time I startup and login. As best as I can tell, it seems OS X checks if an account exists in the Mail app, and if it does not, it will always start up a "Welcome to Mail" dialog on login, regardless if the Mail app is set to run via login items, etc. This is incredibly frustrating given I have no intention of using the Mail app. I realize I can easily leave account info in there (perhaps even disable the account via preferences), but this behavior is ridiculous. ajgs

  • Excel 2010 data validation warning (compatibility mode)

The current LabVIEW software can only handle the legacy .xls format, so we're forced to keep these worksheets as-is for the time being. We've migrated to Office 2010 and when working with these worksheets, I see this warning: "The following features in this workbook are not supported by earlier versions of Excel. These features may be lost or degraded when you save this workbook in the currently selected file format. Click Continue to save the workbook anyway. To keep all of your features, click Cancel and then save the file in one of the new file formats." "Significant loss of functionality" "One or more cells in this workbook contain data validation rules which refer to values on other worksheets. These data validation rules will not be saved." When I click 'Find', some cells that do indeed have validation rules are highlighted, but those rules are all on the same worksheet! We're using simple list-based validation, with some cells off to the side containing the valid values (for example, cell B4 has a List with Source "=$D$4:$E$4") This makes no sense to me whatsoever. One, the workbook was created in Excel 2003, so obviously we couldn't implement a feature that doesn't exist. Secondly, the modifications we're making don't involve changing the validation rules at all. Thirdly, the complaint that Excel is making is incorrect! All of the rules are on the same worksheet as the target. As if the story wasn't bizarre enough: I went ahead and saved the worksheet with Excel 2010. I then went to an old computer back in the lab and opened the document with Excel 2003. Guess what - the validations were untouched! My questions are: is this a legitimate bug in Excel 2010, or is this some exotic error in the legacy .xls worksheet that is confusing the heck out of Excel 2010? Has anyone else observed this issue working in compatibility mode?

  • After update to Windows 8.1 brigthness isn't working (changing)

    - by Bibo
    I just update my Windows 8 to Windows 8.1 by Windows Store and I have some problems. My notebook is Acer Aspire Timelinex 3820TG and I know it's little old for Windows 8 but I install them and works fine (I updated my HDD to SSD). Now I just updated Windows and I have problem with changing brightness on my dedicated graphic card (Ati HD 5650). First I can changing brigthness with fn + keys but It just changing level in OS. No change in real. I tried reinstall drivers, install drivers for my card from Acer with compatibility to Windows 7 and without change. When I switch to integrated card changing brightness works. I think the problem is with drivers but I don't know how to get it working. Thanks for help Bonus question: I have another problem (but this one is not so important). Does anyone knows what msietxghh.exe is doing? Everytime when my system runs (after update) I get message that this program stops working but I just cancel and looks everything works fine.

  • Warning for "Reallocated Event Count" S.M.A.R.T. attribute with a new/unused drive. How serious is t

    - by Developer Art
    I've just looked at the health status of my old 2,5 inch 500 Gb Fujitsu drive with a popular "HD Tune" utility. It shows a warning for the "Reallocated Event Count" property. How serious is that? The thing is that the drive is practically new. I pulled it out of a new laptop over a year ago and never used it since. Right now it only has 53 "Power On" hours which sounds about right since I only had it running a few evenings overnight before switching it for something more performant. Does this warning indicate that the drive is likely to fail some time in the future? I'm somewhat perplexed since the drive is effectively unused. What is more, I have arranged with somebody to buy off this drive since I don't really need. It is 12,5 mm thick (with 3 plates) meaning it doesn't fit into an external enclosure which makes it quite useless to me. Can I give away the drive without having it on my conscience or better cancel the deal? In other words, can the drive be used safely for years to come or better throw it away? I'm running a sector test now to see if there are any real problems. Will post the results as soon as they're available.

  • LDAP Authentication fails with 500 or 401 depending on bind for Apache2

    - by Erik
    I'm setting up LDAP authentication for our Subversion repository hosted through Apache on a RHEL 5 system. I run into two different issues when I try to authenticate against Active Directory. <Location /svn/> Dav svn SvnParentPath /srv/subversion SVNListParentPath On AuthType Basic AuthName "Subversion Repository" AuthBasicProvider ldap AuthLDAPBindDN "cn=userfoo,ou=Service Accounts,ou=User Accounts,dc=my,dc=example,dc=com" AuthLDAPBindPassword "mypass" AuthLDAPUrl "ldap://my.example.com:389/ou=User Accounts,dc=my,dc=example,dc=com?sAMAccountName?sub?(objectClass=user)" NONE Require valid-user </Location> If I use the above configuration it continually prompts me with the Basic prompt and I have to eventually select Cancel, which returns a 401 (Authorization Required). If I comment out the bind parts it returns 500 (Internal Server Error), griping that authentication failed: [Mon Nov 02 12:00:00 2009] [warn] [client x.x.x.x] [10744] auth_ldap authenticate: user myuser authentication failed; URI /svn [ldap_search_ext_s() for user failed][Operations error] When I perform the bind using ldapsearch and filter for a simple attribute it returns correctly: ldapsearch -h my.example.com -p 389 -D "cn=userfoo,ou=Service Accounts,ou=User Accounts,dc=my,dc=example,dc=com" -b "ou=User Accounts,dc=my,dc=example,dc=com" -w - "&(objectClass=user)(cn=myuser)" sAMAccountName Unfortunately I have no control or insight into the AD part of the system, only the RHEL server. Does anyone know what the hang up is here?
