Self registration on openfire server

Hello, I have a server on internet and I would like to allow any user with a client such as "conversation " to self register without the admin. In conversation, there is an option where you can select “register on the server” for the first time you use it after you select “custom xmpp server”…

I am having problem and it looks like it does not work… Can anybody help me and tell me how to do that ?

Thanks

You should enable Inbaund registration in Admin Console. Can’t twll the exact place, but that’s in Server settings, registration and login.
