Unfortunately perdition doesn't currently support that.

However, it shouldn't be too difficult to modify perdition in order to
allow it to check LDAP and them a regex. The main work would be in renaming
some functions as currently popmap modules all provide the same symbols. Or
if things were to be done in a more generic way, use a slightly more
sophisticated module loading mechanism.
