>Description:
Whenever I try to start the Usermin service, Perl coredumps.  Below is the 
stacktrace.  The same thing happens in Webmin, but since PAM is not 
required, the line "no-pam=1" fixes the problem.  Usermin requires PAM, 
however.  I have downloaded pamtester and have been fiddling around and 
can find no problems with PAM itself.  Any help or direction would be 
greatly appreciated.
