I have managed to get the portal initial load working, and it is pulling all the requseted attributes i.e.
However I also need to pull the attribute that stores the mapped user id, which is found in the User Mapping for System Access Tab. I cannot find out what the name of this attribute is or whether it exists in the same table. Does anyone know?
I need this attribute because an ldap backend is used for portal, and ldap does not use the same username as sap backend.
