Postgre security

Hello,

I'm struggling with the methods of user authentication that Postgre uses.
I would like to be able to use the /etc/passwd or /etc/shadow file to
authenticate users.  That way users could easily control their own
passwords by telnet-ing in to the machine.

I've tried the following line in my pg_hba.conf file:

   "local        all                           password /etc/passwd"

But to no good return.  I think that my system (Linux 2.0.34) is using a
different encryption algorithm that Postgre.

For the password "temptemp", my system produces the following:

     "3aBwsRu.LzR4k"

While Postgre's pg_passwd yields:

     "VsHWG150vpTic"


Any insight into this matter would be greatly appreciated.

thanks much,
  Adam
