LDAP Settings (Entourage 2004)

[Gerry Brown]

My IT Department gave me the LDAP search terms in the form of a URL.
e.g. company.com/City/Department

When I set my Search Base to: dc=company,dc=com
I get an empty search result when I search with my first name.

I've tried a myriad of other combinations

cn=people,dc=company,dc=com <- Error -17758
dc=company,dc=com,l=City <- Error -17799

I guess my question are:
1) Can anyone help?
2) Where can I look up the error codes? (At least I could glean some more info).
