Could not bind to LDAP server: Can't contact LDAP server

[shaun connor]

Hello,

I am running Kolab snapshot on a Slackware10 box and I get this error 
"Could not bind to LDAP server: Can't contact LDAP server"
When I attempt to access https://localhost/admin  it will bring up the
kolab graphics and the log in form but without binding to the ldap
server none of this works.
ldap is running on the correct port and I can telnet to it. 
in my apache2 error log.  I get this..

on line 82

if I put session_start()  at the top of ldap.class.php the log reports back...

[client 192.168.0.100] PHP Notice:  Undefined index:  ldap_uri in
/kolab/var/kolab/php/admin/include/ldap.class.php on line 32

on line 82

It's been a real pain getting this to work on Slack and this is what
is tying me up at the moment..  I don't know to much about ldap so any
help at all would be appreciated.
