LDAP in ABAP AS

Hi,

I am trying out the LDAP in ABAP AS and following the document :

http://scn.sap.com/docs/DOC-13976

1. As per the documentation , I have created the RFC Connection ,LDAP connector and LDAP Server and System user . All with the same name.

2. When I try to logon into the LDAP server using LDAP connector, I get "Message no. LDAPRC002", on debugging could make out that the FM:LDAP_COMMONBIND triggers the FM:  LDAPRFC_BIND, which does not exists in the system. Am I missing out anything here?

Thanks
