dovecot - May 2007 - Login with firstname.lastname instead of loginname

Some of our users use to login as
firstname.lastname
or
firstname.lastname at charite.de
instead of using the "correct"
"flastname" login name.

In order to get this behaviour a long-gone co-worker wrote an
authdaemon.pl, which speaks the courier-authdaemon protocol.

How can I emulate this behaviour with dovecot?

Basically, all I need is a usernamen mapping ala:

Ralf.Hildebrandt at charite.de	     rhilde
Ralf.Hildebrandt		     rhilde
for all my users -- I can generate this programatically using awk, but
how can I make dovecot use that?

What passdb are you using? Dovecot supports aliases if you make the
passdb return "user=the-real-user" field.

Hmm, does this mean I add another dummy database containing:

ralf.hildebrandt:user=rhilde
ralf.hildebrandt at charite.de:user=rhilde

for all users? How?
