Active Directory Issues

Hi everyone!

I successfully installed and configured openfire on our server with LDAP Authentication (Active Directory under Windows Server 2008 r2).

Everything works, the admin console login, the spark client login using domain users credentials, chat and file transfer are all fine too until after a few minutes as if something is blocking the communication between the domain and openfire.

It will tell me invalid login when i try to go the admin console although i was able to login a couple of minutes back.

It will disconnect the spark client and logging back in will never happen.

What could be the probable reason for this? It’s like all of the sudden it gets disconnected with the Active Directory.

Kindly tell me the details i need to provide to troubleshoot the issue.

With Regards,
