Re: SAP PI 7.4 -> LDAP connectivity options

I am confused by the 3 links you posted.  2 of the links seemingly talk about linking SAP user accounts/access rights to Microsoft Active Directory via the SAP LDAP Connector:

I only need the ability for PI to do a query against Microsoft Active Directory (no authentication and the user list is not coming from SAP).  Those 2 articles really don't help me unless I missed something while reading them.  Does the SAP LDAP connector allow me to run queiries against Microsoft Active Directory from PI?

The other link is from 2008:

I did read this article.  Is this the only way for PI to just do a query against Microsoft Active Directory?
