Oh! Thank you for that information - I was not aware of that support!
@ Conrad: It is backported to 7.02 if your SP (and kernel) is high enough. If that is the case and an option for you, then it is best to move your question again to the SAP NW SSO forum or keep it here and invite the NW SSO mods to comment so that other folks who search can also find it.
Cheers,
Julius
