[sudo-users] memory fault

I finally figured out what was wrong. I discovered that LDAP was installed 
on this server but wasn't being used. When it was installed it made some 
entries in the pam.conf file which caused the problem. Once I moved the 
original pam.conf file back into place sudo worked fine. Another thing I 
noticed that was caused by LDAP being present was that rather then the 
normal Password: prompt is was System Password:. I'll know next time to 
look for LDAP when I see this. I've seen sudo work fine with the IBM/DB2 
LDAP, but this was HP's LDAP. I'm sure there's a way to get sudo to work 
with HP's LDAP and the entries it makes in pam.conf during installation, 
but fortunately I didn't have to figure it out since LDAP wasn't being 
used on this server - it was just an experiment.

Is the machine where sudo works correctly running the exact same
version of HP-UX as the machine where it gets a fault?

You should be able to build sudo from source on the machine where
the ixpress binary is having problems.  If that shows the same
problem then you've found a genuine bug.
