Change password in AD not affect to openfire

Hi all,

I have Openfire 3.6.4 running on a Debian Lenny system including a Active Directory Authentication. Because we have SSO issues in our domain with sites or whatever, nobody can realy tell me wahts going on, we have no SSO so the users just store their password in the clients.

If a user change his password its not effectet to Openfire. For a short time it seems they can login with their old password and then they cant login with the new or the old password. Clearing the cache makes no difference and restarting the service makes also no difference. What can I do?

If I take a look into the logs it just tell me if a user try a login:

User Login Failed. PLAIN authentication failed

Brgds,

Philip
