Re: fedora and openldap
Have you tried to use the "tls_reqcert never" directive in nslcd.conf
(may not apply in your case ?). I wouldn't run this way, just for
troubleshooting. Also, in nslcd.conf did I see that you changed "ssl
start_tls" to something else. We use "ssl start_tls" in our RH6 boxes.
Also, in nslcd.conf we found success using these directives for RH6 (RH5
uses "nss_base_passwd" type directives):
base group ou=Group,o=example.com
base passwd ou=People,o=example.com
base shadow ou=People,o=example.com
Finally, I'm sure you checked it but with the error below, you should
verify you do not have "uri ldaps://ldap.server.com/" (trailing slash
important) in any of your client config files since you are using
