Only users in the asadmin group are able to access Admin Console and the asadmin command line utility.
To give a user access to these administration tools, add them to the asadmin group in the admin-realm. In the Admin Console, go to Configuration> Security > Realms > admin-realm > Edit Realm > Manage Users. If the user name exists, click on the user name to edit settings or click New to add a new user name.
Initially after installation, the administrator user name and password entered during installation are listed in a file named admin-keyfile. By default, this user belongs to the group asadmin, which gives rights to modify the Application Server. Assign users to this group only if you want to grant them administrator privileges for the Application Server.
If you add users to the admin-realm realm, but assign the user to a group other than asadmin, the user information will still be written to the file named admin-keyfile, but the user will have no access to administrative tools or to applications in the file realm.
To authorize a user to make modifications to the Application Server, include the asadmin group in the Group List.
