SharePoint, Active Directiry Groups and Caching

Posted By:      Posted Date: October 06, 2010    Points: 0   Category :SharePoint
 

Hello.  I support a portal running on SharePoint.  For some of our SharePoint sites that have larger memberships, we manage the membership through AD groups.  In some cases, clients seem to encountering a caching issue.  As user will be added to the AD group, but SharePoint will continue to give that user an Access Denied message to the site.  Other users who are in the AD group can access the site without issue.  In some cases, creating a new AD group, copying the membership of the original group over, and adding that new group to the site permissions resolves the issue, but not always.  Typically, adding the involved user directly to the site permissions resolves the issue for that user.  Can anyone tell me where SharePoint is caching this information and/or what I can do to clear it out?  Thanks!

Building Groups in Active Directory versus Using SharePoint Groups

  

Hi,

Can someone point me to an article or blog that discusses the pros and cons of setting groups (owner, full control, contributor, read only) in the Active Directory verus just connecting MOSS 2007 to the AD and building the groups directly in MOSS?  MOSS 2007 only.  Is there any functionality that is lost by building the groups in AD and adding people there rather than building groups in MOSS and adding people there?

Thanks!


Thanks! Patti N.

Changing an authentication of SharePoint site from SQL-FBA to Active Directory

  
Hi,      We are using MOSS 2007. I have customized a web application using Custom web part, features and ASPX pages. we have configured SQL-Form based Authentication for this site. I have also used FBA user management functionality from Codeplex. I have created some groups and my application (custom aspx page) is referencing these groups to send an email to specific person as per his role for certail events.        I have a requirement to migrate this set up on other server and change the authentication from SQL-FBA to Active Directory. So if I have to change the Authentication from SQL-FBA to AD then what are the steps I have to follow to make this happen?      I would appreciate any help on this. Thanks, Patav    

WebParts with audiences based on SharePoint groups containing AD Groups are not visible.

  
My client has two webparts on a page. Each of the webparts is audienced with a SharePoint group. Each SharePoint group contains one or more AD groups. The groups are not deep nested. I.e. SharePointGroup -----> ADGroup -----> list of user accounts.. When a user in any of these groups browses to the page, they cannot see the webpart. An AD user added to the SharePoint group sees the audiences webpart properly. http://support.microsoft.com/kb/948681 references this issue, however these servers are all recently built with Service Pack 2 slipstream install media, so this hotfix is not valid. They believe that the webparts were working fine previously, but then some ILM work was carried out in the AD over the weekend and it's possible that this has changed some fo the group memberships. Given that we're using SP Groups and AD Groups, Does the actual SSP Import bear any relevance to these memberships or does SharePoint use a (potentially cached) Group memberships object on the SPPrincipal?

Unable to see Active Directory Groups in the User Profile Database after Profile Import

  
SharePoint Server 2010 Enterprise RTM. W2K8R2 w/multi-server setup: AD/DNS SQL 2008 WFE APP Claims Mode Web App only using Windows Integrated Auth So, this was never a problem in 2007, and I didn't even realize it was a problem in 2010 until I started to build a solution that utilized my blog article: InfoPath - User Roles in Browser-Enabled Forms Using AD Groups.  I went to utilize the same web method of the same web service, but I noticed that no data was showing up at all.  Typically, the GetUserMembership/GetCommonMembership methods return the specified user's memberships: AD Security Groups, AD Distribution Lists, and SharePoint Sites (not SharePoint Groups, though). My user profile sync is working.  All AD users are pulled in with the proper profile data. "Users and Groups" is selected in the Synchronization Entities section of my Sync Settings. Security groups are working for permissions and audience targeting.  Confirmed my users are affected properly by the use of Security Groups. My query to the GetUserMemberships web method (and GetCommonMemberships) is running (not failing), but it's not returning anything even though my user is in some Security Groups and has explicit membership to multiple sites. The GetUserProfileByName method of the same UserProfileService.asmx web service returns all the regular profile data

Creating default SharePoint groups for upgraded sites

  

Hello,

I am doing some testing in preparation for a DB attach upgrade from MOSS 2007 to SharePoint Server 2010, and I've run across a bunch of old sites that do not have the default Owners, Members, and Visitors groups. Without those groups (specifically, without Members) we won't be able to take full advantage of the My Sites Memberships page. 

I noticed, though, that when I "Enable Enterprise Features" for all current sites from within Central Administration, sometimes those groups get created on a site that didn't have them before. I've done this on a few different environments and it doesn't seem to always create those groups. Now, I didn't think I had to run Enable Enterprise Features because our 2007 environment was Enterprise, but then I realized some of the sites were created back in SharePoint 2003 and enterprise features might never have been run on the sites when it was upgraded to MOSS 2007. 

So the question: is running Enable Enterprise Features for current sites supposed to create the default groups if they don't exist (along with everything else it does)? Is that the recommended way to get groups made for all sites so site admins/owners can add people to that new Members group which allows the users to visit their My Site page to view all the sites they are members of?

Thanks,
Aaron


Small site embedded login validating against Active Directory and redrecting to SharePoint site

  

I am only finding pieces of this information. 

Challenge: Have a standard page with a login box in the corner that is exposed on the web.  The login will validate an employee against AD and also redirect them to a site collection.

I have found information on claims based authentication and the AD Membership provider.  I have also found information on form based login pages.  Most of these examples though just modify the SharePoint form login.  I want to create just a small login box on a page that is already created.  The one thing that I can't seem to find any really solid information on is the redirect to a site collection.

Can anyone tie all of this together for me?  Am I using the correct terminology and heading down the right path.

Any help is greatly appreciated.

Active Directory last name changed not updated in sharepoint service 3.0 sp2

  

Hello,

we have an active directory member where the last name has changed. However the change is not reflected in sharepoint services sites. When the user opens the sharepoint sites the old last name is displayed. When i look under the properties of the user in sharepoint the last name and the email-adress is still the old one.

How can i correct that?


working with Active Directory groups

  

Hi

I don't know much about active directory groups and programming with AD.  Now I am working on a project which will have 5 to 6 links to otherweb pages and I want to give access to these pages based on the logged in users.

So I am implementing a administration project to give access to these web pages and planned to keep all the application names in one table and all the users in another table. When ever a person or group needs access to a single project, I want to add them through another screen linking users to applications and store it in a table. When user tries opening the web page in the project then it needs to verify the logged in user in the table and display the project if it has a entry for the user with the application.

I am planning to implement some thing like below

Applications Table

ApplicationID

ApplicationName

 

Users Table

UserID

LoginUserName

ADGroup

 

Link Application to User

UserID

ApplicationID

 

When user logs in verify the above table to check if user with the application is available and display the web page required.

 

To do this I need to store all the employees details in the company from different AD groups into the users

SSIS SharePoint List Adapter - how to query Users & Groups?

Sharepoint 2007 - Silverlight - caching issue

  

I have a Sharepoint 2007 site (Custom Template) . The data entry forms are created in Silverlight and host it on Sharepoint.

I use a User Control hosting webpart and host the XAPs.

To be in details : I place the XAP under _layouts. I create a user Control and place at _ControlTemplates and use a Object Tag in the User Control and refer to the XAP. Now on the Sharepoint page I add a (Custom) User COntrol hosting Webpart , refer the User Control (.ascx) , so that my XAp is hosted on the Sharepoint Site.

Problem Statement : I face a refresh problem when I deploy the XAP to _Layouts. When ever I deploy , if I replace my XAp with the latest , the changes in the XAP are not being reflected immediately. i have to restart my Server . instead i am creating a new Directory in _layouts , every time i deploy the XAP and updating the path in the UserControl(.ascx) , which works.

What is solution so that I dont create folders every time i deploy ? Can anyone please help.
