It gives me an error message like, it's not allowed to register such username. But it allows when I enter
ejabberdctl register admin xmpp.domain.com 12345
The problem is...
So basically I can't use username admin@domain.com while using server xmpp.domain.com. What am I missing? any suggestions?
Also I'm a bit confused about SSL config and pem file. My SSL certificate currently supports www.domain.com and domain.com. Do I have to buy ssl cert for xmpp.domain.com also?
