The system is configured as HP-UX 11.0 in trusted system mode, running OpenSSH 
3.5p1 in privilege seperation mode.  If the user is forced to change their 
password it exits immediately.

I have tried using the patch supplied by Damien Miller on HP-UX.  The results 
were the following:

error messages in the syslog.log:
