s2s closes session between two servers, but no user list.

Good morning,

I have 2 installs of openfire.

Server 1 => Linux Cents Version 4.4.2

Server 2 => Windows 2016 cents version 4.6.4

Both successfully closed connection via s2s.

However, I can’t search or view server1’s user from server2, nor does it appear in spark, that is, how do I share groups, so that server1 users talk to server2 users via spark.
