In GW it is possible to have identical usernames in different POs.
GMS1 did not understand this really simple concept.

GMS2 has changed nothing in this respect (It will never). I would understand
if i could authenticate only one User, but what is happening is

User 'A' in PO 'Z' has Password '1'.
User 'A' in PO 'Y' has Password '2'.

First time login to GMS2:
I login as user 'A' with Password '1'! (from PO 'Z')
Guess what: GMS shows the information from user 'A' from the PO 'Y'!

I did not check what information actually gets transferred. I had enough...


PS: What is so difficult about testing...?
