I setup an extranet type portal in DNN 4.9.1 that used AD role synchronization.  I verified that synchronization was working and started working on my site.  Other things drew me away from working on that particular portal and I continued updating DNN and the AD provider (I was actively working on other sites on the same install).  None fo the other sites on the host use role syncrhonization.  I am now using DNN 5.0.1 with the latest AD provider.

I went back to the extranet site yesterday and started actively working on it again.  I have 2 test users in two different Universal Security Groups: rubble is in "Web Sisters" and fudd is in "Web Associates."  Neither one of the users was getting their appropriate content - only content for "Registered Users."  After checking the Roles, I found that both were removed from their roles.  I can't say with certainty, but I think synchronization was still working on DNN 5.0.0.

I've tried the following and all have resulted in removing the user from the role (even after manual addition):

  1. Unchecked synchronize roles, added user to role, logged in and out several times, checked synchronize roles, and was removed
  2. Changed the setup username to a domain admin and repeated 1
  3. Adding user to group and logging out and back in

The only thing that has changed on the domain since going from 4.9.1 -> 5.0.0 -> 5.0.1 is upgrading our Exchange Server from 2003 to 2007.  We're using a Server 2008 domain, with both the forest and domain functional levels at their highest levels.

I had an additional thought on this:  is there some possibility that the LDAP query might not be returning the information?  If I knew the query it was performing, I could inspect the results and see if they were returning what I needed.

There was no difference in the provider from 4.9.1 to 5.0.0 (just minor changes to where the settings were stored in 5.0.0). The version in 5.0.1 had a minor change in role synchronization but that because users weren't being removed from DNN roles when they were removed from AD roles. There was never a problem that I know of adding users to roles. Could you do a test and try change the group to a Global Security Group. It shouldn't make a difference but it's worth a shot.

Mike,

I just solved the problem - and I chalk this one up to not thinking about the simplest solution first.  I grabbed jxplorer to start looking through the LDAP query from my remote server - which is joined to the domain via VPN - and found that it never returned anything.  It just timed out.  So, I started thing, "AH! Firewall!"  Finally, out of exasperation, I restarted the VPN client and everything started moving along.  I couldn't believe how dumb I was - I ran into this 4 months ago and never documented it.  So, I wrote a little PowerShell script that restarts the VPN connection every 24 hours.

But, this does bring up a question: can the AD provider remove you from a role if the query times out?  I imagine that, if you have role synchronization turned on and there's a role synchronization error (in this case a timeout), the provider removes you from the role.  If this assumption is correct, could the provider check for a timeout or...?

Maybe, one day when I have time (in my wildest dreams), I could find the place in the source where this occurs and make a suggestion.

I'm having the same problem but I am not utilizing a VPN between the DNN web server and the AD provider.  I can't honestly say I don't know if my site is having a timeout issue or not but I have a user that is a member of an AD group but they keep getting removed from it automatically in the DNN role that matches that same name. 

Does anyone have any ideas?

I'm kind of a novice so if it helps, I can provide the AD authentication version number I have installed if someone gave me a quick how-to.

Thanks!
