In LDAP version 2, the BindRequest operation must be the first operation performed by an LDAP client. LDAP version 3 removes this restriction; in other words, an LDAP version 3 client can perform directory operations before successfully binding to the directory. Although it is acceptable for an LDAP version 3 server to reject operations from a client that has not bound to the directory first, the LDAP implementation of Microsoft Exchange Server supports LDAP operations from a client that has not successfully bound to the directory.
DPA: password authentication (for MCIS only)
NTLM: for Windows NT client support only
If a username and password are provided (in an octet string), the server checks the user's credentials; otherwise, the user is referred to as an 'anonymous' user.
