I am looking for a jabber server software that can be configured to allow users from multiple servers to communicate with each other and see each other. Based on my poking around it seems like OpenFire will do this (with plugins?) but I wanted to ask to make sure I was not missing/misunderstanding lingo.
Plan is to set up 3 servers, each with it’s own user base but all 3 need to be able to see/chat with users on the other servers. Am I correct that the “clustering” mechanic will allow this to work?
