No: it's the authentication agent/server for the Courier programs.  It 
operates as a separate daemon and provides some service to check who can 
log in, etc.  I don't think it does LDAP itself - just that it can 
communicate with an LDAP server.

I believe the point was so that Courier (the mail server) and Courier-IMAP, 
etc. didn't have to separately implement LDAP/password/etc. for every 
possible user authentication method.

It wasn't hard to use password auth, and I assume they've got LDAP auth set 
up fairly easily as well.  There are guides out there.  Dovecot is slightly 
more straightforward to set up, since it wasn't designed as an add-on to 
something else.
