[Kolab-devel] Roundcube on Debian 12 - LDAP?

Hi,

I've upgraded to Debian12 and have problems logging into roundcube.

I've enabled ldap-Trace in roundcube and see that there is a successful
bind.  But in the roundcube log:

LDAP Error: Could not connect to any LDAP server in
/usr/share/roundcubemail/plugins/libkolab/lib/kolab_ldap.php on line 227
(POST /roundcubemail/?_task=login&_action=login)

The code is this:

      if (!is_resource($this->conn)) {
            rcube::raise_error(['code' => 100, 'type' => 'ldap',
                'file' => __FILE__, 'line' => __LINE__,
                'message' => "Could not connect to any LDAP server"], true);

I've looked at the code for some time and didn's see where $this->conn
is set.  If I remove that code and just accept the first (only) LDAP
server as working I can log in and roundcube seems to work.
The code at that part didn't change recently...

What do I miss? I'm also slightly confused which php-ldap modules are
really neede in the os and what is right now vendored.

Jochen
