[Dovecot] Checkpassword Perl LDAP Implementation

[Jeff Hardy]

A few years back I hacked up a perl chkpassldap.pl script to 
authenticate against ldap, and optionally authorize against groups 
and/or ldap attributes.  This works with both qmail and Dovecot, and it 
also supports a somewhat generic method to alter the environment 
suitable to use for Dovecot as a prefetch userdb.

Anyway, I have been running the script on a qmail-ldap and Dovecot 1.2 
proxying cluster using the stock qmail-ldap attributes without any 
troubles, and figured I would finally release it in the thought someone 
might find it useful.

I tried to document the ins and outs of userdb configuration.  If anyone 
finds anything that could use correction or clarification, please let me 
know.  It has been awhile since I was in the middle of it all.

Cheers,
-Jeff
