jabber and IMP show offline if are registered on different server

[m.cucchi]

Hello i have a IMP V14 cluster in redundancy HA and i have 100 users registered on pubIMP and other 100 users registered on SubIMP , the presence is show as offline if the users are registered on different server.

How i can verify if the problem is related to the server or for user configuration ? 

Thank you

Max

Your problem description is not very clear, who or where the user is seen as "offline" ...
Where do you see the user as "offline"? In the presence viewer? Or does a user assigned to IMP-Pub see a user assigned to IMP-Sub offline (and vice-versa).
