[horde] two different login server with horde 3.0.9

[Michael Jeanrond]

I try to set up a "preauthenticate" hook with two different imap servers in
/imp/config/servers.php (with help of some Documentation and mailing lists), but
when I test the new configuration nothing happenend. Then I tried to set up
"$conf['server']['server_list'] = 'hidden';" for using two different
imapservers, but nothing happenend too.

I using horde 3.0.9 and imp H3 (4.0.4). Has somebody an idea or a solution to
solve this problem?

Thanx.
