Thanks for the explanation.  Though, I would prefer something better
than MD5 since it has been broken for years.

As for my "hack", it doesn't work because I mis-read what %p was,
thinking it was the password, not the column to look for... so back to
the drawing board.  I will look at using something like kerberos, but it
seems like an awful lot of work given my installation requirements.  I'm
up for the challenge, nonetheless.

Thanks again.
