SSHD 3.7.1p2 on HP-UX

   I have a related problem with 3.7.1p2 and HPUX 11.0.  After
I built and installed it, it doesn't work.  And I don't get any
useful info in my syslogs.  We use PAM heavily
(we use DCE behind the scenes), so we are NOT using trusted mode
or shadow passwords.  The /etc/password file just has asterisks
in the password field because authentication goes thru PAM.
3.6.1p1 works fine with this setup.

My sshd_config file is attached.  The same config file and 3.7.1p2
works great on Solaris 7/8/9.  Is the a bug or a config problem?
