S2S user authentication

My problem.

How do I get the users to see and join the chat rooms on the server at the another site?

User-01 connects to server 1, adds server 2. The user can see the chat rooms on server 1 but not server 2

User-02 connects to server 2, adds server 1. The user can see the chat rooms on server 2 but not server 1

Spark shows conference.serverA.domin.int and conference.serverA.office.domin.int

Setup

FQDNs

Server 1 - serverA.domain.int

Server 2 - serverB.office.domain.int

XMPP Domain name

Server 1 - serverA.domain.int

Server 2 - serverB.office.domain.int

ldap.baseDN

Server 1 – domain.int

Server 2 - office.domain.int

I know this will pull far to much information but it will do for testing, will reduce it one the servers go live

All servers are 2012R2

Databases MS SQL2017 Express

ServerA uses domain.int

ServerB uses office.domain.int

Openfire version 4.2.3

Spark Ver2.8.3

Servers configured for S2S using the FQDNs

Both servers set to “allow peer certificates to be self-signed”

Firewall configured to allow all traffic between the servers
