  • ADSIEdit freezes gettings properties of a group with hundred of thousands members

    - by ixe013
    Doing performance testing on an AD-LDS (Server 2008 R2 64 bits), we created a milion user in a single OU. We also created a single group object and made those milion users member of that group. When we try to list the milion of users ADSIEdit times out with an error message saying it cannot display that many users. Fine. But if we open the properties for the group, ADSIEdit freezes, eating up all available memory and CPU trashing (nearly 60M page faults in under an hour). AD-LDS (running on another computer) is barely hitting the 1% CPU mark, servicing other ldap requests as if nothing were. We can throw more memory at the problem, but more users will have to be managed one day and we will be back at square one. Is there a way to set a limit in ADSIEdit so that it will not hang the computer when retreving a very large multi-value object ?

  • Managing access to multiple linux system

    - by Swartz
    A searched for answers but have found nothing on here... Long story short: a non-profit organization is in dire need of modernizing its infrastructure. First thing is to find an alternatives to managing user accounts on a number of Linux hosts. We have 12 servers (both physical and virtual) and about 50 workstations. We have 500 potential users for these systems. The individual who built and maintained the systems over the years has retired. He wrote his own scripts to manage it all. It still works. No complaints there. However, a lot of the stuff is very manual and error-prone. Code is messy and after updates often needs to be tweaked. Worst part is there is little to no docs written. There are just a few ReadMe's and random notes which may or may not be relevant anymore. So maintenance has become a difficult task. Currently accounts are managed via /etc/passwd on each system. Updates are distributed via cron scripts to correct systems as accounts are added on the "main" server. Some users have to have access to all systems (like a sysadmin account), others need access to shared servers, while others may need access to workstations or only a subset of those. Is there a tool that can help us manage accounts that meets the following requirements? Preferably open source (i.e. free as budget is VERY limited) mainstream (i.e. maintained) preferably has LDAP integration or could be made to interface with LDAP or AD service for user authentication (will be needed in the near future to integrate accounts with other offices) user management (adding, expiring, removing, lockout, etc) allows to manage what systems (or group of systems) each user has access to - not all users are allowed on all systems support for user accounts that could have different homedirs and mounts available depending on what system they are logged into. For example sysadmin logged into "main" server has main://home/sysadmin/ as homedir and has all shared mounts sysadmin logged into staff workstations would have nas://user/s/sysadmin as homedir(different from above) and potentially limited set of mounts, a logged in client would have his/her homedir at different location and no shared mounts. If there is an easy management interface that would be awesome. And if this tool is cross-platform (Linux / MacOS / *nix), that will be a miracle! I have searched the web and so have found nothing suitable. We are open to any suggestions. Thank you. EDIT: This question has been incorrectly marked as a duplicate. The linked to answer only talks about having same homedirs on all systems, whereas we need to have different homedirs based on what system user is currently logged into(MULTIPLE homedirs). Also access needs to be granted only to some machinees not the whole lot. Mods, please understand the full extent of the problem instead of merely marking it as duplicate for points...

  • How many users can be in a AD LDS group?

    - by ixe013
    Microsoft published the recommended maximum limits for users in an Active Directory group. It basically says : Starting with Windows Server 2003, the ability to replicate discrete changes to linked multivalued properties was introduced as a technology called Linked Value Replication (LVR). and This allows the number of group memberships to exceed the former recommended limit of 5,000 for Windows 2000 or Windows Server 2003 at a forest functional level of Windows 2000. Given the replication meta data below, can anybody tell me what is the maximum number of users a AD-LDS group can hold ? Getting 'CN=Member,CN=Schema,CN=Configuration,CN={67B333FE-ADB4-430D-AAEE-D4CCE4B98A2E}' metadata... 23 entries.

  • Managing Active Directory Group Membership with a Non-Administrator Account In Server 2008

    - by Laranostz
    I am running Server 2008 R2 in an Active Directory Domain Environment. I have created a group in Active Directory and I have delegated management authority to that group to a user. I want this user to be able to add and remove accounts as needed from that group so that they are exercising some measurement of control without giving them other authority. When I have the user attempt to access the Active Directory Users & Computers Console it prompts them for Administrator credentials. They are using Remote Desktop to access the server, because they do not have Windows 7, and firewall rules prevent using the Remote Management Kit. I do not want to provide them with any level of Administrative rights except the minimum required for them to add/remove users from this group. There are two servers that 'talk' to each other in this isolated environment, a domain controller and a member server, both are only reachable through RDP. Any suggestions?

  • Freebsd Secondary Group not allowing folder deletion

    - by Jarrod Juleff
    TLDR: I have a user that is a member to a group as a secondary group. This user can delete files with 664 perms as a secondary user, but not directories with perms of 775. Details: I have a user. Lets call him ftpuser. I use him to upload and download files to my devbox. The user's primary group is "ftp" and is also in the group "www" as a secondary group. My web server runs as user www and group www, and I have proftpd (running as www and www) configured to drop all files into the needed directories as www and www (for file ownership) and perms 664 on files and 775 on directories. My problem is (tried with 2 ftp clients) the ftp client can delete the files, but not the folders. Filezilla returns 550 permission denied. The owner only can delete flag is not set, and I've triple checked the permissions and they are indeed 775. Its driving me nuts to have to log into my server to manually delete folders every time. Some of the folders and files are created by 1 of my php scripts, but the permissions are getting set properly when I check the files' properties. Directory and file creation works phenomenal. Can delete files, just not directories. Freebsd 9.0 Running in VirtualBox (32bit all the way around) Proftpd (running as www and www) as ftp server (tried using both dreamweaver and filezilla as the clients) Basic amp setup (apache,mysql,and php).

  • McAfee Security Scan appears out of thin air

    - by Jacques
    Hi, We have a Windows Server 2008 Standard edition server and when we logged in today a service, McAfee Security Scan, had been installed. I checked all the logs, but can't find any trace of who or how this install was initiated. We already use Nod32 so there would be no reason for us to install McAfee. Any idea how this happens? I did look for other installs like Flash or the like, but didn't see anything. Thanks Jacques

  • Unix users and permissions and how they interact with web files.

    - by Columbo
    Hello, When you issue the command ls in Linux you get this sort of thing: drwxr--r-- 1 fred editors 4096 drafts -rw-r--r-- 1 fred editors 30405 file1.php -r-xr-xr-x 1 fred fred 8460 file2.php I know that the rwxrwxrwx are the read, write and execute permissions for the current user. And I think I know that 'fred' is the user who owns the file. So I assume fred can write to file1 but no one else can. But what is the extra bit 'editors' and what is the difference between file1 and file2 with respect to one having an ownership of 'fred editors' and the other 'fred fred'? Also if a web user connects to one of the files, what is their user name and where is this decided? If the server decided that user connecting from the web was going to be fred, does this mean any web user could write to file1? Any information welcomed, I am resaerching this but just getting confused. Thanks

  • Users can't change password trough OWA for Exchange 2010

    - by Rémy Roux
    Here's our problem, users who want to change their password trough OWA get this error "The password you entered doesn't meet the minimum security requirements.", even if users are respecting the minimum security requirements. With these settings, we have the error: Enforced password history 1 passwords remembered Maximum password age 185 days Minimum password age 1 day Minimum password length 7 characters Password must meet complexity requirements enabled With these test settings, we don't have an error: Enforced password history not defined Maximum password age not defined Minimum password age not defined Minimum password length not defined Password must meet complexity requirements not defined People can change their password but there is no more security! Just changing one parameter of the GPO for example "Enforced password history", brings back this error. Here's our server configuration : Windows Server 2008 R2 Exchange Server 2010 Version: 14.00.0722.000 If anybody has a clue it would very helpful !

  • Deployment and Ownership issues

    - by kylemac
    As an extreme newbie, I am having difficulty managing ownership and permissions on my first box. What I can't figure out is how to deploy using one user, we will call him deploy and operate my php application with www-data user. Currently as it stands, I know my server runs as www-data through this function <?php echo(exec("whoami")); ?> but I am having to chown between deploy and www-data every time I deploy. There has got to be an easier way to deploy with one user and still run as www-data. EDIT: Here is the output from ls- l on the folder in question. You will see user deploy and group www-pub, the group is from an attempt to add the two different users to a new group and chown one of them in the hopes that they both would have the permissions (newb alert) drwxrwxr-x 4 deploy www-pub 4096 Mar 7 01:41 example.com I am using capistrano for deployment under the user deploy then once its done i chown to www-data, otherwise I can't use php to manipulate files. I am also unsure how to even change which user apache is running.

  • Secure Server Distro

    - by Drama
    Hello, I have a root-server (i7/24GB/1TB) running Ubuntu 10.04 LTS as my OS. After some security audits (OpenVAS, Retina etc) I see that Ubuntu isn't the most secure system for a semi-corporate environment. Its updated from many sources, ofc from the Ubuntu security repo too. But nevertheless I could exploit my OpenSSL install with an exploit from August/September. There are some critical updates needed which Ubuntu does not provide. I was using Debian and Ubuntu for almost 5 years but now I doubt. What distro is secure and up to date from your point of view? How can I make the server more secure? Outsourcing of every software-module to a VM? I am not new to server-hardening, my packages are up to date I read Ubuntu Security Notices and I have no unneeded services installed on my server. Thanks.

  • Jail Linux user to directory for FTP login

    - by Greg
    I'm planning on using vsftpd to act as a secure ftp server, but I am having difficulty controlling the linux users that will be used as ftp logins. The users are required to be "jailed" into a specific directory (and subdirectories) and have full read/write access. Requirements: - User account "admin_ftp" should be jailed to /var/www directory. - Other accounts will be added as needed, for each site... e.g: - User account "picturegallery_ftp" should be jailed to /var/www/picturegallery.com directory. I have tried the following, but to no avail: # Group to store all ftp accounts in. groupadd ftp_accounts # Group for single user, with the same name as the username. groupadd admin_ftp useradd -g admin_ftp -G ftp_accounts admin_ftp chgrp -R ftp_accounts /var/www chmod -R g+w /var/www When I log into FTP using account admin_ftp, I am given the error message: 500 OOPS: cannot change directory:/home/admin_ftp But didn't I specify the home directory? Extra internets for a guide how to do this specifically for vsftpd :)

  • Grant relay to servers based on AD security group membership

    - by john
    We're moving our relay from an Exchange 2003 server to an Exchange 2010 server. I was hoping the "Grant or deny relay permissions to specific users or groups" option would still be available in some form, but I can't find out how to do it. I've read up on recieve connectors and so far I can't get it to work. I have edited the security on the Recieve Connector to allow the following extended rights to the group and added computer accounts to that group: Accept Routing Headers Bypass Anti-spam Submit to Server Accept any Sender Accept any Recipient Then I suddenly realised while testing... How would the receive connector resolve the permission to a particular AD object, maybe a reverse DNS lookup? What I'd like to know is if what I'm trying to achieve is possible, and how it would be possible. I would rather not revert to an IP-based list as this is not as manageable, and I'm trying to avoid creating static IPs/reservations for a number of workstations that would otherwise not need them.

  • How to limit access to Exchange 2003 Mobile Activesync server by user?

    - by micilin
    So I was asked to set up an Exchange Activesync mobile gateway. That's done. It's a separat eExchange 2003 front-end server configured for SSL, and I've put an off-domain ISA server in front of it. Now I'm being asked to limit which users can connect to it. By default an Exchange front-end server allows any user who has a mail account to connect to the front -end server. So I'm looking at the permissions on the various IIS sites/apps on the server, but I know that it's easy to break Exchange Front-end server perms. So I've got the following in IIS: Exadmin Exchange EchWeb Microsoft-SErver-ActiveSync MobileAdmin OMA And a couple of others that I dont think are relevant. Can I change the permissions on one of these to restrict who can connect to Activesync? As a bonus: Can I do it in a way that does not affect ordinary browser based Exchange Access? Thanks in Advance!!

  • On Windows Server 2003, permissions are not propagating to a group that is a member of a group

    - by Joshua K
    Windows Server 2003 on i386. FTP server is running as the SYSTEM user/group. Some files we want served (read and write) are owned by the group 'ftp.' ftp has full read/write/whatever permissions on those files and directories. SYSTEM can't read/write those directories. So, I added SYSTEM to the 'ftp' group. Windows happily complied, but even after restarting Filezilla, it still could not read/write those files. Is there any way to do what we want without "re-permissioning" all those files? Running the ftp server as 'ftp' isn't really an option because it also serves files that are owned by SYSTEM (And not ftp). Sigh... :) Any insights?

  • Redundant APC UPS units, single server set up

    - by Sholom
    Hi All We have a very simple set up, looking for a very simple (reliable) solution: Setup: One Dell box with redundant power supplies running Windows 2003, plugged into two separate APC SmartUPS 1500 units (USB, no smart cards) on two separate circuits. Solution required: IF (UPS1 = Low) AND (UPS2 = Low) THEN: Shutdown gracefully ELSE: DO NOTHING!! APCUPSD only allowes for one instance (and therefore one UPS) in a windows environment. PowerChute can't do this without using APC Smart Cards which means utilizing our switch, but the switch does not have redundant power supplies, so it will only live for as long as one of the two UPS units. And no, i don't have the budget to buy two smart cards pluse a switch with redundancy ;) Thanks

  • Is a reboot required to refresh permissions after adding a user to a new group?

    - by Michael Prescott
    On ubuntu server, I've noticed more than once now that after adding a user to a group that user doesn't have group permissions until I reboot the system. For example: User 'hudson' needs permission to read directory 'root:shadow /etc/shadow' So I add hudson to the shadow group. hudson still cannot read. So, I 'sudo shutdown -h -r now' and when the system comes up again user hudson can read. Is a reboot required or is there a better way to get permissions applied after adding the user to the group?
