1.3. Security Changes
Overriding the default JAAS realm in Fabric
In JBoss A-MQ 6.2, the rank of the default
ZookeeperLoginModule JAAS module (which is installed by default in a Fabric container) has changed to 99, and the name of the default realm is karaf. In previous releases, the rank of ZookeeperLoginModule realm was just 1.
Hence, if you want to override the default
karaf in the context of Fabric, you must define a new realm named karaf, with a rank attribute that is greater than or equal to 100.
Enabling LDAP authentication in a Fabric
In particular, this change affects the configuration needed to enable LDAP authentication in a Fabric. In this case, the
rank attribute of the jaas:config element in the JAAS realm configuration file must be increased to at least 100 (recommended is 200). For details, see section "Procedure for a Fabric" in "Security Guide".
