ACS 4.0 and AD

[clyde.wilson]

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.

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.
