With the LDAP Admin Tool, it works with port 636 doing SSL/TLS too. I will be making the production connection use that, as soon as I get the non SSL/TLS 389 to work.

I’ve also used the admin credentials with ldapsoft.com <http://ldapsoft.com/> <http://ldapsoft.com/ <http://ldapsoft.com/>> ’s LDAP Admin Tool, and my credentials test correctly, and I get a full list of users in the table view. I’m not sure what else to try here.

I tried with substituting uid= for cn= in LDAP Admin Tool, and it doesn’t like like it, saying the credentials are invalid.

and I tried changing the uid= for cn= in the filter section of the mods-available/ldap file, no dice.
On the OneLogin server, it shows a successful VLDAP login for the admin user admin at iacollaborative.com <mailto:admin at iacollaborative.com> every attempt, but nothing for the dward@ user.
