PROBLEM:  (Patch ID: OSF410-081)
********
When there is a large number of user entries in /etc/passwd,
/usr/sbin/removeuser, by calling /usr/sbin/mkpasswd, would take a long time 
to rebuild the hashed database file.  /usr/sbin/removeuser now calls 
/usr/sbin/userdel which updates the hashed password database directly
without the need to rebuild the database.
