cups ldap

[wes]

Trying to get cups to bind to LDAP to find a list of printers available, from which jobs can be sent to.

First off, is this even supported?

Secondly, here is my ldap config:

BrowseLDAPServer ldap://servername:3268
BrowseLDAPDN cn=noc-clbfp1, ou=fp, ou=servers, ou=clb, dc=clubs, dc=domainname, dc=com
BrowseLDAPBindDN ldap_proxy
BrowseLDAPPassword password

When I start cups everything appears to be fine, when I try to search for printers I get the following:

E [10/Apr/2008:10:14:22 -0700] LDAP search returned error -1: Can't contact LDAP server
E [10/Apr/2008:10:15:12 -0700] LDAP search returned error -1: Can't contact LDAP server
E [10/Apr/2008:10:19:20 -0700] LDAP search returned error -1: Can't contact LDAP server

When I start cups I see the following:

We are using cups-1.3.6-1 on RHEL 4u6.

I am not really sure if what we are trying to do is what the ldap directives where intended for. But we set BrowseRemoteProtocols to ldap and disabled everything else to force Cups to look to the directory service for printers. We don't want to register local printers, just connect to remote printers.

BTW: The remote print servers are on an Active Directory domain, so we are defining the print server that controls all of the printers. If we attach the printer via an smb:// ldap connection in the cups printers.conf it works fine, but remote browsing seems to break.

Thoughts?
