AD userid will not access CatOS devices via ACS

[cdrobey]

I am unable to logon to any CatOS devices via ACS, using AD userids. I am able to logon to IOS devices with the AD userids. I was able to logon to CatOS previously (for the last year) with the AD userids. I am not sure what changed. I created local Cisco database accounts in ACS, and it autenticates just fine. Please assist.

Thanks

Did you upgrade the CatOS or the OS of any other box ?

I resolved the issue. My tacacs timeout was set for two seconds. I changed it to five seconds and the devices are authenticating now. Thanks for responding.
