I've tried it in interactive and non-interactive mode. The non-interactive result is shown:
Roberts-MacBook-Pro:bin robertmonical$ ./add-user.sh manager changed
* Error *
JBAS015243: The user 'manager' already exists in at least one properties file.
I have searched everywhere in http://localhost:9990/console and cannot find a user admin utility.
It appears to me that there is no way to change a user's password. I can manually delete the user from the properties file(s) and then add it again. Is this true?
This is odd enough to me that I thought I would ask the question before logging an issue.
The documentation here appears to be incorrect about the ability to modify a password:
https://docs.jboss.org/author/display/AS71/add-user+utility
There was a related 7.0.x discussion in 2012 that implied user management was in the console and it apparently suggested a modification to the stanalone.xml file. Mine was different enough I did not poke around. This is my management tag in my standalone.xml
-<management>
-<security-realms>-
<security-realm name="ManagementRealm">-
<authentication>
<properties relative-to="jboss.server.config.dir" path="mgmt-users.properties"/>
</authentication></security-realm>
-<security-realm name="ApplicationRealm">-
