LDAP Attribute in SAP Ticket

Hi,

i want to put the content of a LDAP attribute into the SAP ticket INSTEAD od the user id.

As far as I know, it is possible to put a LDAP Attribute into the Ticket in addition to the user ID. But then I have to go with an reference system. My problem is, that i can not implement a reference system for various reasons.

I have got the user id of the user in his various sap systems (same id in every system i has to access). I want to put this in a LDAP attribute and send it with the SAP ticket.

Regards
