I have this issue on Openfire 4.0.1 (32 bits) and 4.2.3 (64 bits) version.
I used admin console to create a group, added owner, admin and member. However, after a restart I found there is additional 1 or 2 members added automatically in owner, admin and member sections.
How come? This will cause privacy issue as chat message will be delivered to unexpected members. Anyway to fix this ? Urgent…
