dovecot - Jan 2011 - Login with firstname.lastname instead of loginname - WORKING

3 years ago (!) I aksed about this and finally I implemented it today:
>>   # NEW
>>   passdb {
>>      driver = passwd
>>      # firstname.lastname at
charite.de:password:uid:gid:(gecos):home:(shell):user=realloginname
>>      args = /usr/local/etc/dovecot.login_via_email
>>   }
>If you're only using it as a passdb, you don't need the
uid/gid/home. So
>an example field would be:
>
>firstname.lastname at charite.de:password::::::user=realloginname
But now I'm encountering problems with users writing

Firstname.Lastname at charite.de
instead of
firstname.lastname at charite.de
(capitalized first letters)

How can I "normalize" the usernames by lowercasing them?

The coolest solution would be to strip realms AND force lowercasing of
usernames in one pass

Not tested, but hunch tells me something like:

 args = username_format=%Ln

should work.

Yes, that worked like a charm!
Now we were able to switch from an old courier-pop + patched
authdaemon to dovecot for ALL services!

Out of curiousity, given a userbase the size you have, why are you using 
unix users rather than say LDAP or SQL?

Traditional reasons. This system was installed over ten years ago and
was changed over time. 

We first started with courier (I think?) or uw-imap (I have no idea -
mists of time and all that)

I just asked a colleague who still had the old docs I wrote ages ago. But
those were discarded when he changed offices.
