In JBoss 6.2 domain environment if in the host.xml file on the slave is missing the realm in the domain-controller tag as reported below

<domain-controller>
<remote host="10.123.137.200" port="9999"/>
</domain-controller>

we get the following error:

Adding the realm everything works correctly

<domain-controller>
<remote host="10.123.137.200" port="9999" security-realm="ManagementRealm"/>
</domain-controller>

Maybe a warning message could be useful to find the problem.
