• SharePoint 2010 User Profile Sync - Remove Disabled Users

  - by ScaleOvenStove

  I have SharePoint 2010 set up to sync active directory users and it is working great. I am getting disabled users in the sync though. I have tried what all the blogs say, filter on userAccountControl bit on equals 2 but to no avail, the disabled users are still syncing. I am at a loss on where to look next. My last resort would be to create a ou/folder in AD and move disabled users there and remove that from the sync connector, but I don't really want to go there. Any ideas?

• User Already Exists in the Current Database - SQL Server

  - by bullpit

  I was moving a lot of databases from one SQL Server to another, and my applications were giving me errors saying "Login failed for <user>". The user was already in the database with appropriate rights to allowed objects in the database. I tried mapping the user to the database and that's when I got this message: "User Already Exists in the Current Database"... I googled and found this very useful post about orphaned users when moving databases. These are the steps you should take to fix this issue: First, make sure that this is the problem. This will lists the orphaned users: EXEC sp_change_users_login 'Report' If you already have a login id and password for this user, fix it by doing: EXEC sp_change_users_login 'Auto_Fix', 'user' If you want to create a new login id and password for this user, fix it by doing: EXEC sp_change_users_login 'Auto_Fix', 'user', 'login', 'password'

• Installing MoinMoin -wiki to my user directory on a server with no root access

  - by deiga

  Hello all, I posted this on webapps, but they told me to come here :) I've been trying to install MoinMoin -wiki on this webserver, where I have no root access. The server doesn't support wsgi, but it does support cgi/fcgi/etc. I've scoured google for a simple guide on how to accomplish this, but the only guides I found were from the year 2004 or so. Other guides always assumed that one has root access. So can anyone link a good tutorial for my question or just help me out here? Your help is appreciated :) P.S. Sorry if this is the wrong stack -page

• List all BPM Processes for a user

  - by kasriniv

  Hello, Happy to start contributing to this blog..  The title of the blog is probably deceptively simple and warrants an elaboration. Customized BPM workspaces/user interfaces are a fairly common requirement. One of our marquee customers in the online stock trading business, envisioned this user interaction for their BPM application: User logs in to the internal portal Use will have list of roles which he is granted as a drop down list Once user selects the role, a list of processes which user is part of appear. Logged in user can be part of any swimlane role of the process This can be a fairly common/reasonable user-UI interaction pattern. 1. and 2. are easily achievable and hence the subject matter of this blog is the requirement in 3. Objective: Given a username and a role, list all the BPM processes that the user is part of, in any swimlane of any process. Here is quick overview of the major steps/logic in the code: Intialize workflow/BPM  context as usual Get a handle on InstanceQueryService(getInstanceQueryService), InstanceManagementService,        ProcessMetadataService and ProcessModelService List all Processes for that bpmcontext (listProcessMetadataSumary) and get Granted roles to that user For each of the processes [method  getAccessibleProcesss(ProcessMetadataSummary, Set)]for each of the lanes in the process, check if the role granted to the user, matches the roleName for that swimlane. If so, add to output. Notes: The usual caveats apply including BPM APIs are subject to change.  JDeveloper method introspection is your better friend than API documentation :-)... (I am going to try upload the source code  and if it doesnt work, will follow this blog up with the corresponding source code.) Hope this helps.  Ack: Yogesh K, BPM Dev team.

• Samba users not added untill they logon first? Edit: How do I add users to tdbsam without a password prompt?

  - by glisignoli

  I add users to my server with the command useradd -m -p PASS_HASH -s /usr/sbin/nologin USERNAME Then I try to access their samba home share, but it never shows up until I login with the user: root:~$sudo login failtest Password:###### Added user failtest. Is there some way of added the user without logging in? Edit: The problem is that the user is added with the useradd command, but ubuntu seems to run an initalisation script when the user logs on for the first time. This script then adds that user to the tdbsam user database. Finding the initalisation script or the method it uses to add a user to the tdbsam database without requiring any user input (as smbpasswd -a USER prompts the user for a password). So all I need is a way to add a user+pass to the tdbsam database without prompting a user for a password (eg: samaba-add-user.sh USERNAME PASSWORD).

• Limit number of concurrent user logins in Windows Server 2008 Active Directory

  - by smhnaji

  Is there the possibility to limit Active Directory users' max concurrent login sessions? I've read many articles and discussions about the solution, but none of them seem to be working. Many had suggested UserLogin script that doesn't work in Windows Server 2008. Some other suggested CConnect that is not good enough. It's also very complicated. Some others have introduced UserLock that should be paid for. It's wondering that Windows Server 2003 DOES have the feature (wile as a third-party), but Windows Server 2008 doesn't have! One of the articles I've read: http://www.edugeek.net/forums/windows-server-2008-r2/61216-multiple-logins.html

• Change AccountName/LoginName for a SharePoint User (SPUser)

  - by Rohit Gupta

  Consider the following: We have an account named MYDOMAIN\eholz. This accounts Active Directory Login Name changes to MYDOMAIN\eburrell Now this user was a active user in a Sharepoint 2010 team Site, and had a userProfile using the Account name MYDOMAIN\eholz. Since the AD LoginName changed to eburrell hence we need to update the Sharepoint User (SPUser object) as well update the userprofile to reflect the new account name. To update the Sharepoint User LoginName we can run the following stsadm command on the Server: STSADM –o migrateuser –oldlogin MYDOMAIN\eholz –newlogin MYDOMAIN\eburrell –ignoresidhistory However to update the Sharepoint 2010 UserProfile, i first tried running a Incremental/Full Synchronization using the User Profile Synchronization service… this did not work. To enable me to update the AccountName field (which is a read only field) of the UserProfile, I had to first delete the User Profile for MYDOMAIN\eholz and then run a FULL Synchronization using the User Profile Synchronization service which synchronizes the Sharepoint User Profiles with the AD profiles. Update: if you just run the STSADM –o migrateuser command… the profile also gets updated automatically. so all you need is to run the stsadm –o migrate user command and you dont need to delete and recreate the User Profile

• 2011 Tech Goal Review

  - by kerry

  A year ago I wrote a post listing my professional goals for 2011.  I thought I would review them and see how I did. Release an Android app to the marketplace – Didn’t do it.  In fact, haven’t really touched Android much since I wrote that.  I still have some ideas but am not sure if I will get around to it. Contribute free software to the community – I did do this.  I have been collaborating with others via github more lately. Regularly attend a user group meetings outside of Java – Did not do this.  Family life being what it is makes this not that much of a priority right now. Obtain the Oracle Certified Web Developer Certification – Did not do this.  This is not much of a priority to me any more. Learn scala – I am about 50/50 on this one.  I read a few scala books but did not write an actual application. Write an app using JSF – Did not do this.  Still interested. Present at a user group meeting – I did a Maven presentation at the Java user group. Use git more, and more effectively – Definitely did this.  Using it on a daily basis now. Overall, I got about halfway on my goals.  It’s not too bad since I did do a few things that weren’t on my list. Learned to develop applications using GWT and deploy them to Google App Engine Converted one of my sites from PHP to Ruby / Sinatra (learning to use it in the process) Studied up on the HTML 5 features and did a lot of Javascript development

• Why is this simple file upload not working? JSF

• How to export and import an user profile from one Quassel core to another?

  - by Zertrin

  I have been using Quassel as my bouncer for IRC for quite a long time now. We (a group of administrators of a small network) have set up a shared Quassel core with many users on the same core. But now I would like to export everything related to my user account from the Quassel database on this core, in order to re-import it later in another Quassel core on my own server. Unfortunately, while a feature for adding users has been implemented into Quassel, nothing is so far provided for either exporting or deleting an user. (if deleting-a-user feature was available, I could have made a copy of the current database, delete all the other users leaving only mine, and use this resulting database on my own server, while leaving the first one untouched on the shared server) Despite extensive research on the Internet on this subject, I've found so far no solution. I have to precise that the backend database for the core has been migrated from the default SQLite backend to a PosgreSQL backend as the database grew sensibly (over 1,5 GB for now). However I'd be glad to hear from any working solution (SQLite or PostgreSQL backend) describing a way to export the data related to a specific user profile and then re-import-it in a new Quasselcore database.

• JSF: How to get the selected item from selectOneMenu if its rendering is dynamic?

  - by Dzmitry Zhaleznichenka

  At my view I have two menus that I want to make dependent, namely, if first menu holds values "render second menu" and "don't render second menu", I want second menu to be rendered only if user selects "render second menu" option in the first menu. After second menu renders at the same page as the first one, user has to select current item from it, fill another fields and submit the form to store values in database. Both the lists of options are static, they are obtained from the database once and stay the same. My problem is I always get null as a value of the selected item from second menu. How to get a proper value? The sample code of view that holds problematic elements is: <h:selectOneMenu id="renderSecond" value="#{Bean.renderSecondValue}" valueChangeListener="#{Bean.updateDependentMenus}" immediate="true" onchange="this.form.submit();" > <f:selectItems value="#{Bean.typesOfRendering}" /> </h:selectOneMenu><br /> <h:selectOneMenu id="iWillReturnYouZeroAnyway" value="#{Bean.currentItem}" rendered="#{Bean.rendered}" > <f:selectItems value="#{Bean.items}" /> </h:selectOneMenu><br /> <h:commandButton action="#{Bean.store}" value="#Store" /> However, if I remove "rendered" attribute from the second menu, everything works properly, except for displaying the menu for all the time that I try to prevent, so I suggest the problem is in behavior of dynamic rendering. The initial value of isRendered is false because the default item in first menu is "don't render second menu". When I change value in first menu and update isRendered with valueChangeListener, the second menu displays but it doesn't initialize currentItem while submitting. Some code from my backing bean is below: public void updateDependentMenus(ValueChangeEvent value) { String newValue = (String) value.getNewValue(); if ("render second menu" == newValue){ isRendered = true; } else { isRendered = false; } } public String store(){ System.out.println(currentItem); return "stored"; }

How I can achieve this in .Net ?

• How do you encourage users to fill out their profile?

  - by mattdell

  Hello, I wanted to open up the topic to discuss ways to encourage or incentivize users to fill in information in a user profile on a website, such as skills, location, organization, etc. More information in a user profile can give a website an improved capability for its users to search, network, and collaborate. Without bugging users to fill in their profiles (ie - via annoying e-mail reminders), what other ways have you guys come up with to encourage user input? Best, -Matt

• User controls in masterpage and anonymous user

  - by Senad Uka

  I am developing a master page which includes the user control that generates a menu from the list with a specific logic. Before including the control into master page I successfully configured anonymous access to the site. After including the control and deploying - site prompts for user name and password. I allowed the anonymous access to the list. Oh yes ... It worked on SHarepoint 2010 beta, but the problem happens when deploying to the Sharepoint 2010 final release. Additional data: I am using Sharepoint Server 2010 with Standard features, standalone instalation on Windows Server 2008 R2 for deployment, and Visual Studio 2010 Ultimate for development of masterpage and user control.

• How to record when user follows external links without slowing user down

  - by taw

  I want to track when user clicks external links for analytics purposes. The simplest solution is to replace all external links with links to special record-and-redirect controller, but that would slow the user unnecessarily. The second idea would be to override click event and within in $.post a message to record controller, then let the main event handler happen, which will usually be either click (open link in same tab) or middle click (open in new tab) - good either way, and the user won't have to wait for wait for my server to record it, it's fire-and-forget. (I don't care if users without Javascript don't get tracked) Is that a reasonable way to go? Or what else would be the best way to track all external link clicks?

• Refactoring multiple if statements for user authentication with subdomains

  - by go minimal

  I'm building a typical web app where once a user signs up they access the app through their own subdomain (company.myapp.com). The "checking what kind of user if any is logged in" piece is starting to get very hairy and it obviously needs to be well-written because its run so often so I was wondering how you guys would re-factor this stuff. Here are the different states: A user must be logged in, the user must not have a company name, and the sub-domain must be blank A user must be logged in, the user must have a company name, that company name must match the current sub-domain A user must be logged in, the user must have a company name, that company name must match the current sub-domain, and the user's is_admin boolean is true if !session[:user_id].nil? @user = User.find(session[:user_id]) if @user.company.nil? && request.subdomains.first.nil? return "state1" elsif [email protected]? if @user.company.downcase == request.subdomains.first.downcase && [email protected]_admin return "state2" elsif @user.company.downcase == request.subdomains.first.downcase && @user.is_admin return "state3" end end end

• MS Dynamics CRM users disappear

  - by Max Kosyakov

  Recently we came across quite a weird issue. The administrators say that once in a while they notice that user accounts in MS Dynamics CRM are lost . When a new user is added to the system, the administrators add him/her to the Active Directory first. Then, they go to Dynamics CRM interface, then to system configuration -> administration -> users and add the new user to the CRM, add roles to this user, grant them relevant permissions. Then the user is able to use a custom application, which connects to the Dynamics CRM via WCF. After a while (few weeks or months) the user is unable to use the custom application because Dynamics CRM cannot authorise this user. When administrators open the Dynamics CRM user management interface (configuration -> administration -> users ) and browse through the list of CRM users they cannot find the user in the list. When they try to add the user to Dynamics CRM back, the CRM fails with the error message "User already exists". Moreover, the user still exists in the Active Directory. The admins are very sure the user had been added to the CRM before he/she started to work. The only fact the the user was able to use the custom application normally says that the user had been indeed registered in the CRM. How come the user is not listed in the CRM user management interface at all? Have anyone faced any issues like that? Seen or heard of disappearing CRM users somewhere? Any help is appreciated. Where can one start digging?

It should fire only once as long as i am on same page beacause my bean is @ViewScoped. Further, if i remove the binding attribute then everything works fine and @PostConstruct callback fires only once. Then why every time when i use binding attribute? I need binding attribute and want to perform initialisation tasks like fetching data from webservice, etc only once. What should i do? Where should i write my initialisation task?

• What are the principles of developing web-applications with action-based java frameworks?

  - by Roman

  Background I'm going to develop a new web-application with java. It's not very big or very complex and I have enough time until it'll "officially" start. I have some JSF/Facelets development background (about half a year). And I also have some expirience with JSP+JSTL. In self-educational purpose (and also in order to find the best solution) I want to prototype the new project with one of action-based frameworks. Actually, I will choose between Spring MVC and Stripes. Problem In order to get correct impression about action-based frameworks (in comparison with JSF) I want to be sure that I use them correctly (in bigger or lesser extent). So, here I list some most-frequent tasks (at least for me) and describe how I solve them with JSF. I want to know how they should be solved with action-based framework (or separately with Spring MVC and Stripes if there is any difference for concrete task). Rendering content: I can apply ready-to-use component from standard jsf libraries (core and html) or from 3rd-party libs (like RichFaces). I can combine simple components and I can easily create my own components which are based on standard components. Rendering data (primitive or reference types) in the correct format: Each component allow to specify a converter for transforming data in both ways (to render and to send to the server). Converter is, as usual, a simple class with 2 small methods. Site navigation: I specify a set of navigation-cases in faces-config.xml. Then I specify action-attribute of a link (or a button) which should match one or more of navigation cases. The best match is choosen by JSF. Implementing flow (multiform wizards for example): I'm using JSF 1.2 so I use Apache Orchestra for the flow (conversation) scope. Form processing: I have a pretty standard java-bean (backing bean in JSF terms) with some scope. I 'map' form fields on this bean properties. If everything goes well (no exceptions and validation is passed) then all these properties are set with values from the form fields. Then I can call one method (specified in button's action attribute) to execute some logic and return string which should much one of my navigation cases to go to the next screen. Forms validation: I can create custom validator (or choose from existing) and add it to almost each component. 3rd-party libraries have sets of custom ajax-validators. Standard validators work only after page is submitted. Actually, I don't like how validation in JSF works. Too much magic there. Many standard components (or maybe all of them) have predefined validation and it's impossible to disable it (Maybe not always, but I met many problems with it). Ajax support: many 3rd-party libraries (MyFaces, IceFaces, OpenFaces, AnotherPrefixFaces...) have strong ajax support and it works pretty well. Until you meet a problem. Too much magic there as well. It's very difficult to make it work if it doesn't work but you've done right as it's described in the manual. User-friendly URLs: people say that there are some libraries for that exist. And it can be done with filters as well. But I've never tried. It seems too complex for the first look. Thanks in advance for explaning how these items (or some of them) can be done with action-based framework.

• Technical Article: Oracle Magazine Java Developer of the Year Adam Bien on Java EE 6 Simplicity by Design

  - by janice.heiss(at)oracle.com

  Java Champion and Oracle Magazine Java Developer of the Year, Adam Bien, offers his unique perspective on how to leverage new Java EE 6 features to build simple and maintainable applications in a new article in Oracle Magazine. Bien examines different Java EE 6 architectures and design approaches in an effort to help developers build efficient, simple, and maintainable applications.From the article: "Java EE 6 consists of a set of independent APIs released together under the Java EE name. Although these APIs are independent, they fit together surprisingly well. For a given application, you could use only JavaServer Faces (JSF) 2.0, you could use Enterprise JavaBeans (EJB) 3.1 for transactional services, or you could use Contexts and Dependency Injection (CDI) with Java Persistence API (JPA) 2.0 and the Bean Validation model to implement transactions.""With a pragmatic mix of available Java EE 6 APIs, you can entirely eliminate the need to implement infrastructure services such as transactions, threading, throttling, or monitoring in your application. The real challenge is in selecting the right subset of APIs that minimizes overhead and complexity while making sure you don't have to reinvent the wheel with custom code. As a general rule, you should strive to use existing Java SE and Java EE services before expanding your search to find alternatives." Read the entire article here.

• UI message passing programming paradigm

  - by Ronald Wildenberg

  I recently (about two months ago) read an article that explained some user interface paradigm that I can't remember the name of and I also can't find the article anymore. The paradigm allows for decoupling the user interface and backend through message passing (via some queueing implementation). So each user action results in a message being pased to the backend. The user interface is then updated to inform the user that his request is being processed. The assumption is that a user interface is stale by definition. When you read data from some store into memory, it is stale because another transaction may be updating the same data already. If you assume this, it makes no sense to try to represent the 'current' database state in the user interface (so the delay introduced by passing messages to a backend doesn't matter). If I remember correctly, the article also mentioned a read-optimized data store for rendering the user interface. The article assumed a high-traffic web application. A primary reason for using a message queue communicating with the backend is performance: returning control to the user as soon as possible. Updating backend stores is handled by another process and eventually these changes also become visible to the user. I hope I have explained accurately enough what I'm looking for. If someone can provide some pointers to what I'm looking for, thanks very much in advance.

• User defined type for healthcare / Medical Records variable name prefixes?

  - by Peter Turner

  I was reading Code Complete regarding variable naming in trying to find an answer to this question and stumbled on a table of commonly accepted prefixes for programming word processor software. Well, I'm not a word processor software programmer, but if I was, I'd be happy to use those user defined types. Since I'm a programmer for a smallish healthcare ISV, and have no contact with the larger community of healthcare software programmers (other than the neglected and forsaken HealthCareIT.SE where I never had the chance to ask this question). I want to know if there is a coding convention for medical records. Like Patient = pnt and Chart = chrt and Medication = med or mdctn or whatever. I'm not talking full on hungarian notation, but just a standard that would fit in code complete in place of that wonderful chart of word processor UDT's which are of so little use to me.
