I am facing couple of issues:

 1) There is an error displayed in the Authentication Settings,

Error: is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Unknown error (0x80005000) ---> System.Runtime.InteropServices.COMException (0x80005000): Unknown error (0x80005000) at System.DirectoryServices.DirectoryEntry.Bind(Boolean throwIfFail) at System.DirectoryServices.DirectoryEntry.Bind() at System.DirectoryServices.DirectoryEntry.get_IsContainer() at System.DirectoryServices.DirectoryEntries.ChildEnumerator..ctor(DirectoryEntry container) at System.DirectoryServices.DirectoryEntries.GetEnumerator() at DotNetNuke.Authentication.ActiveDirectory.Settings.CheckPipelineMode() at DotNetNuke.Authentication.ActiveDirectory.Settings.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---

I tried configuring it several times but still have the above error. Note: Everything works fine, users can login and acces the contents in the website, but icant get rid of the above error.

2) Another issue is that, DNN Database does not get updated when i make changes in active directory.

For Example: When i change the email address of an employee in Active Directory, the DNN database does not get changed. It displays the previous email id in the DNN profile of an employee.

Please help me to solve the above issues. Thanks in advance!

I am using impersonation, still have same problems.

SERVER OS: Windows Server 2008 Standard, DNN Version: 5.0.2, The error is always displayed when i login as host and browse to Admin-->Extensions-->DNN ActiveDirectory Authentication Extension Settings.

The main problem is that the changes in Active Directory does not synchronize with DNN database
