Have you got the localhost method working under RU5? I have tried configuring GUPs using this method, which worked very well before, and my RU5 system does not seem to like it. The clients with the LU policy containing localhost as the GUP do not become GUPs any more. Clients, GUP candidate and SEPM are all on RU5.
I have looked at the GUP list method but wanted to avoid the clients deciding which GUP to use, themselves - preferring to specify this explicitly through policy.
Any help appreciated.
