As part of a 1000 user CRM 2011 implementation, we need few clarifications

1.Is CRM 2011 LDAP v3 complaint?

2.Can ADFS 2.0 (Active Directory Federation Services) authenticate with Novell eDirectory directly or it can only authenticate with Active Directory?

3.Can we implement CRM 2011 in claim based authentication as
  CRM 2011 -> ADFS 2.0 ->  Novell eDirectory.
That is without using Novell’s STS (Security Token Service) the Novell Access Manager?

4.If we implement CRM 2011 in claim based authentication as
  CRM 2011 -> ADFS 2.0 -> Novell Access Manager -> Novell eDirectory,
do we still need to install Active Directory? If required, for what purpose it is required?

Thanks and Regards,
