Im using phpBB 3.2 and while trying the yabber function I encountered this debug error and functional problems.

[phpBB Debug] PHP Warning: in file [ROOT]/includes/functions_jabber.php on line 573: stream_socket_enable_crypto(): Peer certificate CN=`danwin1210.me' did not match expected CN=`danwin1210.me.danwin1210.me'

Which is strange since I have specified the yabber settings as follows.

Jabber server:danwin1210.me
Jabber username or JID:username
Jabber password:password
SSL: Off

Using this server with SSL on Pidgin shows that danwin1210.me uses a valid and verified SSL certificate.

It`s as if phpBB things it has to verify danwin1210.me, but instead tries to verify "danwin1210.me.danwin1210.me" for some reason.

As in this example I have not selected SSL, But phpBB3 still connects and checks its cert. I guess this is a yabber server-side function of forcing SSL.

But when I do try to select SSL in acp for this module I simple get a connect error.

Could not connect to Jabber server.

Error: open_socket() - Connection refused

Error: connect() #2

Summary:

1: Validating to wrong domain or the validation function is not working in phpBB.
2: The SSL function in the modules does not work, non-ssl function requests server cert instead. Like the switches for hot and cold have been labelled wrong.

Fixes: Found this which seems to be spot on.
