Spacewalk client OSAD service SSL error

I have some problems with my freshly Spacewalk setup.

I have registered my test client, and installed osad service to avoid executing rhn_check.

But when I start osad service, I get the following error:

Starting osad: Not able to reconnect
Traceback (most recent call last):
File "/usr/share/rhn/osad/jabber_lib.py", line 253, in setup_connection
c = self._get_jabber_client(js)
File "/usr/share/rhn/osad/jabber_lib.py", line 320, in _get_jabber_client
c.connect()
File "/usr/share/rhn/osad/jabber_lib.py", line 604, in connect
raise SSLDisabledError
SSLDisabledError
[  OK  ]

I try to start osad with command osad -v and I get the following:

2014-11-06 11:26:26 jabber_lib.setup_connection: Could not connect to any jabber server

Spacewalk server have jabberd and osa-dispatcher running properly, and listening on port 5222/TCP

Also, I'm able to connect to Spacewalk's port 5222 via telnet from client machine.

Both machines have iptables disabled and SELinux in permissive mode.

Any help would be greatly appreciated.

Kind regards. Miguel
