S2S key verification and Shared Groups Between Two Domains

Hello!

I have very strange behaviour of my two openfire servers that makes me crazy in last week.

In first “LOCAL” server (im.neuron.ru) i create two Groups and enable group sharing to each other:

“Office1” Members: pavel@im.neuron.ru and ivan@im.neuron.ru

“Office2” Members: olga@im.land.ru and anna@im.land.ru

In second “REMOTE” server (im.land.ru) i create the same two Groups and enable group sharing to each other:

“Office1” Members: pavel@im.neuron.ru and ivan@im.neuron.ru

“Office2” Members: olga@im.land.ru and anna@im.land.ru

The problem starts here:

Then i trying in LOCAL server to APPLY any changes in “Contact List (Roster) Sharing” menu,

**such as Add\Remove users in group belonging to remote server or **

Somebody can help me solve this problem?
I can’t sleep, just eat!!!

In local-server (im.neuron.ru) debug log i see this information:
