UCS LDAP Configuration

Folks,

I have a question re: LDAP for UCS. 

Does anyone know, if in the lab we get tasked to do an LDAP config, whether we will be told the BaseDN is a CN= or an OU= ?

This is quite important information, as it will directly affect the LDAP configuration within your provider group (BaseDN) and also any LDAP group maps which may need to be configured?

Depending on how the AD is set up, the BaseDN could start with either a CN= or an OU= ??

I have LDAP setup in my lab with the BaseDN being an OU= , but I see  in the UCS workbook, the LDAP config is for a CN=

(I can't get onto my lab at the moment to test!!).

Thanks

Dominic
