Attributes for Exchange 5.5 Mailboxes : ADSPath
This is no real LDAP attribute, it's rather an interface property of the ADSI object representing the mailbox recipient. This 'attribute'
has nothing to do with the LDAP server - it is provided by the ADSI interface. The property 'ADSPath' contains a complete LDAP path name string for the mailbox object, including the server address. For example:
|Data type||ADSI Interface Property -> String|
|Interface documentation||Microsoft - MSDN|
Since this is no real LDAP attribute, you cannot use ADSPath in any LDAP filter!
