Nice to see your serverback up again.

Same feeling here. A trip into the woods in southern germany made connections to the net difficult

I use the Gentoo-overlay. I thought the only difference would be the way the files are installed. So I guess I should use the "gentooish" howtos. Where do I find the one for setting up Horde with Kolab on gentoo? I just can't find one on
http://docs.pardus.de/.
Ah ok. Yes, actually the explicit horde documentation is still missing. Currently I am still to busy patching the system, but I hope to be able to write that soon.
EDIT: My /var/www/kolab/htdocs/horde/config/kolab.php looks like this (I use it for testing only in my private LAN, hence the TLD "test"), so I guess this is fine.
<?php
$conf['cookie']['domain'] = abfax2.treehouse.test;
$conf['problems']['email'] = 'postmaster@treehouse.test';
$conf['problems']['maildomain'] = 'treehouse.test';
$conf['kolab']['ldap']['basedn'] = 'dc=treehouse,dc=test';
$conf['kolab']['ldap']['binddn'] = 'cn=manager,cn=internal,dc=treehouse,dc=test';
$conf['kolab']['ldap']['bindpw'] = 'XXXXXXXXXXXXX';
$conf['kolab']['ldap']['phpdn'] = 'cn=nobody,cn=internal,dc=treehouse,dc=test';
$conf['kolab']['ldap']['phppw'] = 'XXXXXXXXXXXXX';
$conf['kolab']['imap']['server'] = 'abfax2.treehouse.test';
$conf['kolab']['imap']['maildomain'] = 'treehouse.test';
$conf['kolab']['imap']['adminpw'] = 'XXXXXXXXXXXXX';
?>
Ah ok, that looks ok. Since you use Gentoo this is already in the new format. In that case you need to add the manager entry in /var/www/kolab/htdocs/horde/config/conf.php.
This is the example from a demo machine:
$conf['auth']['admins'] = array('wrobel@demo2.pardus.de');
Cheers,
