2162289 - User mapping with ABAP user data source in SPNego configuration

• You configure your SAP AS Java to use SPNEGO.  The KERBEROS token received (in webdiagtool trace) has a userprincipalname.
• The user datasource of the engine is ABAP and you have different user IDs in LDAP server and ABAP system.
• You need to do the user mapping in new SPNEGO wizard. ABAP user attribute “SNC” is chosen to do the user mapping and it fails.
• Error below is found in webdiagtool trace:

07:22:20:089 Error J2EE_GUEST HTTP Worker....core.server.jaas.SPNegoLoginModule Could not validate SPNEGO token.

[EXCEPTION]
