Failed to start/stop child containers after changing admin password

Issue

• I change the default admin password as:

JBossFuse:karaf@root> jaas:realms
Index Realm                Module Class
1     karaf                io.fabric8.jaas.ZookeeperLoginModule
JBossFuse:karaf@root> jaas:manage --index 1
JBossFuse:karaf@root> jaas:useradd admin newP@ssw0rd
JBossFuse:karaf@root> jaas:update

• And also restarted the root container. I can create the new container and stop it. But I am getting the SecurityException while stopping the child containers that are already created before password change.

JBossFuse:karaf@root> container-create-child root pqr
Jmx Login for root: admin
Jmx Password for root: 
Creating new instance on SSH port 8103 and RMI ports 1101/44446 at: /home/cpandey/NotBackedUp/Development/JBoss_Fuse_Folder/jboss-fuse-6.3.0.redhat-310/instances/pqr
The following containers have been created successfully:
    Container: pqr.
