BES 5 environment
 

we have 3 clusters. 1 in the north and 2 in the south, we dont want to remove\delete the one in the north as some users is connected to it, but we dont want to move those users to the south clusters.
how can i disable new user creations on the server in the north? server admin should still be able to do admin stuff on the server. but no new user creations.
