admin password
One answer
can the admin password be changed?
Yes, it can.
If you are using standalone LDAP registry , well you have to change it in your LDAP
but i am guessing you are using a File based security, in which case there is a file containing users and passwords.
Search for a file named user.props in the <WAS\profiles\profileName\config\cells\cellName\props
Note that its not recommended to to change any existing user names.
Passwords can be changed.
For a production environment, its not recommended to use File based.
