Hi Paul,

I believe that you can get what you are after by adding the
username_from_database option to your perdition configuration file (not the
popmap) or specifying --username_from_database on the command line.

Also, depending on how many real-servers you have, you may find the POSIX
Regular Expression popmap useful for this kind of mapping. For example, it
would save you needing an entry per-user if they all map to the same
real-server and domain.

# cat /etc/perdition/popmap.re
