Cant contact LDAP server

Asked by Mark Fuller on 2007-10-31

Ubuntu server 7.10
Followed server software install documentation on https://help.ubuntu.com/7.04/server/C/openldap-server.html

Installed init.ldif without error (used custom DIT structure).

Ran ldapsearch as specified (substituting my details) and got error "ldap_bind: Can't contact LDAP server (-1)"

Tried searching some forums, but got nowt. Any suggestions?

Thanks for you question. Can I ask to post you ldap.conf and your slapd.conf. I want to know if you want to use samba like PDC. Thanks

P.S. I don't use samba. What's PDC?

Mark Fuller (mark-nurse) said : #4

tried:
#netstat -ant | grep 389
no results

stopped slapd with
#/etc/init.d/slapd stop

restarted it with
#slapd -h ldap/// ldaps:///
it worked!
ldapsearch returned my name.

edited ldap.conf
changed to:

URI ldap:/// ldaps:///

stopped & restarted without -h option - it worked!

Thanks are due to my mate Andy
