Goal: The goal is to prevent the caching of domain credentials (however they're stored). We will still maintain one or two local accounts that are cached, in the event offline administration is necessary.
I am at a loss. I am not experienced with CentOS or Linux in general, so I'm fumbling my way around.
authconfig --test shows

From that point I moved on to PBIS. I saw there's a PBIS config entry for CacheEntryExpiry. It was set to the default value of 14400 (seconds), so I set it to 5, logged off, waited a few minutes, rebooted the entire OS, and (with the NIC disconnected) was able to successfully log on with my domain credentials.
What piece(s) am I missing?
