The problem was that the mysql user names and permmisions where not set currently, once I fixed this it ran just perfect.
This happens when the /etc/hosts file on master and slave are not exactly as described in the tutorial. Common mistakes are that not all servers of the clusters are configured there or that the file contains lines that contain maore names then the fqdn of the nodes. Examples:
192.168.0.1 server1 server1.domain.tld
With the wrong entry, mysql will not be able to authenticate the slave.
