Shared group does not work

Good day! Openfire 3.9.3 installed on debian. Authorization through AD. Gave the name to the group, fumbled. Spark connected. Group shows a list of users in the offline visible, but users who go online in it. Messages arrive. If add a person to your friends list, it is normally displayed.

There is an old version on Windows all the settings 1 to 1, everything works fine, reinstalled several times. Prompt please, what can I do?
