Changing the super administrator password WSO2 IOTS 3.1.0 - wso2-iot

Question

I dowloaded WSO2 IoT Server 3.1.0-M8 version. I want to change super admin password and I followed the instructions in documentation
Changing
the Super Administrator Password and in tab 'Changing Password via
file configuration'. I have changed admin password to new one in all
configuration files mentioned in documentation. I've also changed
[wso2iothome]/conf/api-manager.xml by replacing ${admin.password}
entries with my new password. I connect to ApacheDS LDAP server and
get super admin user successfully. I have changed passwords in the
Property name="ConnectionPassword"> entry in user-mgt.xml file. I
started server by running start-all.sh in Ubuntu 14.04 LTS machine. It
gives following error:
