weblogic nodemanager password change methods

I
Edit WLS config.xml and edit thelines:
<node-manager-username>weblogic</node-manager-username>
<node-manager-password-encrypted>{AES}WIoQZoc+EIlXEHfqVnNq68K9LGvtO90SsjRg62Z1LI0=</node-manager-password-encrypted>

II
Go to directory: domain_directory/config/nodemanager
Take a backupof file: nm_password.properties
Find an entry hashed=uFiKcLvYU3x9r11u8tjZlRvwBr4\= and remove it
add credentials in simple text:
password=
username=

III
Log in to Admin Console and go to: DomainName -> Security tab-> General tab -> Advanced Options. Then change the property Credentials with the new password.

IV
Also, in order to verify your changes you can connect to your Node Manager using the new credentials:
1 $ cd */oracle_common/common/bin
2 $ wlst.sh
3 wls:/offline> nmConnect(domainName='robin_domain', username='User123', password='password123')
4 Connecting to Node Manager ...
5 Successfully Connected to Node Manager.
6 wls:/nm/test_domain> nmDisconnect()
7 Successfully disconnected from Node Manager.
8 wls:/offline> exit()

AuthenticationEnabled to “false” in the nodemanager.properties file to ignore what we are passing as part of user and password while connecting to the node manager. 

managed server not starting via nodemanager: ensure that the admin's ldap is copied over managed server's ldap.
