Are you using a AD for the users?

Mar 21, 2011 15:13

Yes, we are using AD and we got problem after we migrated (change domain). We hava more than 500 users and I still can't understand why just few of them got the error. Especially when all the user are in the same domain and groups.

Petter - Do you have a clue?

Hmm. Was thinking it could be the blank space or invalid char issue in the AD provider first but after a second glance I see that the stack trace doesn't match.

I would try and isolate what users that get the error and then try and find out what is unique with them.

Perhaps they are all part of a group that isn't synced into the server and then System.Security.Principal.SecurityIdentifier.Translate can't find it. (just guessing here)
