[Cialug] pam troubleshooting

[Matt Patterson]

what you can do is trace the process that you are connecting to.  That 
might show the missing library or config file.

Do the following:

strace -f -s512 -p <PID>

You'll see a whole bunch of stuff flying by when you go through the 
connection process.   If it is a missing file, you will see an 
open("filename_here")
and then an error about a missing file a few lines later.
