How to determine patch level?

[Riggs, Joan]

How can I determine the patch level of AFS 3.4a running on a Solaris 2.6
server?

I am getting the following message and wonder if anyone knows what this
means:

pam_afs:  Password required but not supplied by user uucp
pam_afs:  Password required but not supplied by user lp

This started at midnight and is recurring every few minutes.

        THANKS!
