Hi there,

All of a sudden one my boxes does not allow correct logins. When I try to login my username/password it states: "Error in service module". I have tried booting in single user mode and changed the password for both root and my account but that doesn't work. After doing some googling, it seems that my pam module could be the problem. Anyone have an idea on how to fix this? thanks!

This is on a redhat 7.2 distro.

Did you make any changes, installed or removed SW or configs? Did you check the system state by verifying it with the rpm databases contents (rpm -Va)? Could you post the contents of the /etc/pam.d/login and system-auth and actual error message?

Hi Unspawn,

Thanks for the reply. I forgot to mention that the only thing I did was put the NIC into a different PCI slot. That's all. There were only 2 pci slots on the board and 1 of them got bad for no reason that I could find. So I moved the NIC to the other PCI slot and the machine booted up just fine (Redhat Interface said everything was [OK]). Wouldn't that be ok? Below is the information you requested.

----/etc/pam.d/login----

As for doing 'rpm -Va' I get a lot of:
'.....T'
Any symbols that I should recognize as being critical or problematic? Thanks very much!
