ldap to authenticate

[Darci Tartari]

As I could see in horde.php configuration file it's possible to use ldap 
to authenticate the imp user's and I'm thinking to use that...

Is there anybody who could give me an example how I can configure horde 
to use ldap at localhost.

I am  running Horde 2.1-cvs, IMP 3.1-cvs and Turba 1.1-cvs, PHP-4.1.1 
with FTP, Ldap, Gettext, IMAP, MCAL, Mcrypt, MySQL, PostgreSQL, XML 
support modules, apache 1.3.22 +mod_ssl 2.8.5 in a FreeBSD 4.4 box.

Thanks a lot !
