Feedback on the Password Policy/Password Changer Webpart

Jul 25, 2008 at 9:25 AM
I've successfully installed the Webparts and trying to use the Password Policy Webpart.
It seems to work on the first sight but if i try to change my password it throws

"Exception has been thrown by the target of an invocation."

after i click on the change button. The TamTam Log shows the following entries:

25-07-2008 11:15:39   GetDirectoryEntryByLDAP User found:testsp2
25-07-2008 11:15:39             GetADProperty PasswordExpirationDate = 10/23/2008 11:14:10 AM for user testsp2
25-07-2008 11:15:39 System.Reflection.TargetInvocationException Exception has been thrown by the target of an invocation.
   at System.DirectoryServices.DirectoryEntry.Invoke(String methodName, Object[] args)
   at TamTam.SharePoint.WebParts.ActiveDirectory.SetADPassword(String domain, String user, String oldpassword, String password)

Can anybode confirm this ?
Does anybody know what the problem is and could help me to fix this ?

Thanks in Advance......
