ACS 4.0 and AD

I have 2 ACS 4.0 servers that are in production. Every 4 to 5 weeks user are suddenly unable to authenticate using EAP-TLS. When I check the failed attempts log the error message is "external user not found". I reboot the servers and everything is fine for another few weeks. Any ideas on why this happens would be appreciated. Thanks.

Re: ACS 4.0 and AD

Hi

Do you reboot the ACS server or the AD server that ACS is talking to? Or, are they the same box?

Sounds like a potential memory/handle leak issue if consistanly re-occurs after the same period.

There's a lot of new (read that any way you like) code in 4.0. Wouldnt be at all suprised to find there are leaks.

I reboot the ACS server. I have no access to our AD domain controllers.
