My goal is to prepare some jobs locally, before to push them to minions.
On the same machine, i try to use master and syndic
My master is listenning on 0.0.0.0 port 4505
I've installed salt-syndic, with syndic_master on 127.0.0.1 and order_masters: True.

On the master, when i do the following:
salt '*' test.ping, i got:
root@salt-master:/home/menil# salt '*' test.ping
test-salt:
    True
test-salt:
    True
test-salt:
    True

When i do that, i was attended to have response from the salt-master (which is syndic too).
And the log are plain of the following :
2014-03-28 08:30:05,552 [salt.master                                 ][ERROR   ] An extra return was detected from minion test-salt21.corp.domisys.com, please verify the minion, this could be a replay attack

Any ideas on how to proceed?
