Hi,

I'm trying to implement SOGo on top of my mail system which is already
using MySQL to auth users. The idea is that anyone with a mail account
has access into SOGo. I've created a view on the auth table which
matches what SOGo is expecting, but unfortunately my passwords are
stored in md5crypt, a system which SOGo doesn't recognize.

I thought about switching my crypt system to straight md5, but I thought
it would be nice if SOGo could support md5crypt and thereby not require
my users to change passwords. I tried to figure out how I could make
that happen using the OpenSSL libs, but I couldn't figure it out.

Instead, I just made a call to the system crypt(), which is different
depending on what OS you're on, but most of them (all of the ones I use)
support md5crypt. I can't imagine I'm going to be the only person in
this situation so I thought this, or something that accomplishes this
but is actually written by someone who knows what they're doing in objc,
would be something useful in future versions of SOGo.

The patch is at the end of this message. It warns about an implicit
declaration of crypt, something I haven't figured out how to get rid of
in this situation.
