LDAP and Symposium Web Center Portal 4.0

[Skaret]

Hi!

I try to set up my SWCP 4.0 using LDAP to Exchange 5.5 server.

Questions:
Q1: Do I need to set the username and password to log onto the LDAP (Exhange 5.5)? In the DTR it says not required..
Q2: When configuring the LDAP on the SWCP-server I need to set up the "Search Base Value". What do I enter here and where can I find the information on the Exchange 5.5?

Thanks in advance!
