how to configure WAS to stop application server without prompting for password even though security is enabled

1. If you are using the SOAP connection type (default) to stop the server, edit the following file:
   

profile_home\properties\soap.client.props

Then, change the values of these properties:
com.ibm.SOAP.securityEnabled=true
com.ibm.SOAP.loginUserid=
com.ibm.SOAP.loginPassword=

Again, the user ID , with its password , is the user ID with Administrator role rights or the primary administrative user name defined in the user account repository.

2. We recommend that you encode the com.ibm.SOAP.loginPassword propertyvalue using:

\bin\PropFilePasswordEncoder.bat soap.client.props com.ibm.SOAP.loginPassword
Examine the result and remove the backup file, soap.client.props.bak, created by the command used previously. It contains the unencrypted password.

3. Try stopping the JVM, without giving user id and password.
