UserPrincipal.GetAuthorizationGroups Method ()
Returns a collection of principal objects that contains all the authorization groups of which this user is a member. This function only returns groups that are security groups; distribution groups are not returned.
Assembly: System.DirectoryServices.AccountManagement (in System.DirectoryServices.AccountManagement.dll)
Return ValueType: System.DirectoryServices.AccountManagement.PrincipalSearchResult<Principal>
A collection of Principal objects that contain the groups of which the user is a member, or null if the user does not belong to any groups.
The attempt to retrieve authorization groups failed.
The retrieval of authorization groups is not supported by this operating system.
This method searches all groups recursively and returns the groups in which the user is a member. The returned set may also include additional groups that system would consider the user a member of for authorization purposes.
The groups that are returned by this method may include groups from a different scope and store than the principal. For example, if the principal is an AD DS object that has a DN of "CN=SpecialGroups,DC=Fabrikam,DC=com, the returned set can contain groups that belong to the "CN=NormalGroups,DC=Fabrikam,DC=com.
