Bummer. Not even on weak reply or guess. I suppose that's something.
I found a little time today to troubleshoot this issue, but I've not found the cause of home dirs automouting.
I'm sure it's something we've done that's not directly related to RHEL, but I'm not certain yet. We're fairly new to RHEL as we've been in Solaris-land forever.
I was thinking it might be a cron of other service, but nothing proves to solve the issue yet.
I've tried temporarily turning off crond, snmpd, snmptrapd, auditd, and a few others. The NIS user dirs keep mounting every 5 minutes. Of course restart/killing autofs corrects the problem.
I've just never seen this type of behavior in Solaris. It's our first time using NIS on Linux. I guess this is why I decided to test a few servers before relying on it heavily. It's a closed private network that's why we've chosen to stay with NIS to help serve out developer/admin authentication.
I'll update this WHEN I find the culprit, even if it's our own configuration/scripts somewhere, which I'm sure it must be.
