The following happens with current Spark 2.5.8 and OF 3.4.3.
User “Support1” is part of Group “Support” and this group is shared to ALL.
User TIM sees “Support1” in his roster (due to shared to ALL) and starts a chat.
Support1 gets a chat window and they chat along nicely BUT in the title bar of this window the presence “light” is OFF, i.e. TIm is reported as OFFLINE!
However the existence of an ongoing chat as well as the admin gui shows TIM as being online.
-> So it comes down to: “Why does Support1 does not see the Presence of TIM??”
P.S. Support1 and TIM are at two different LAN-interfaces as the OF-server is dual homed.
