I'm trying to go through about 11K users and retrieve their authorization Groups from Active Directory using UserPrincipal (C#, .NET 6):
PrincipalSearchResult<Principal> groups = up.GetAuthorizationGroups();
I've noticed that I'm getting the following error:
An error (5) occurred
on some of the users.
Later on I've noticed that I'm getting the same error, but on different users each run.
Furthermore, up.GetGroups() works every time.
I assume GetAuthorizationGroups takes longer, and by activating it on 11K users one by one I'm getting a timeout or something in that area.
Is there anyway to make it more efficient? Am I in the right direction?
I'll add that this process should take no longer than 30 minutes, so I used Parallel.Foreach on a bulk of 20 users.
Thank you in advance.
