using LDAP with MS ACTIVE DIRECTORY

Hello List,

We are planning to move away from oracle names server and wanted to make use of LDAP facility with MS ACTIVE DIRECTORY. I have the following doubts in this regards:

1. Do we have to create any schema for database in the Active Directory , as when I try to use directory usage configuration, it complains that I dont have schema for the database.
2. I dont need to make use of OID(oracle Internet directory), rather I would like to use MS Active Directory option.
3. Does OID required or I can go with MS Active Directory with LDAP?

You suggestion or any docs for this procedure would be a great help for me.

Thaning you in advance
