Error 403: AuthorizationFailed

Error 403: AuthorizationFailed

After starting MXServer (or any other Application Server in WebSphere), you get the following error:

Error 403: AuthorizationFailed

This is because you have Application Server Security configured in your environment and there seems to be an issue with Security role to user/group mapping configuration.

Solution:

1. Login to WebSphere
2. Stop the application server (MXServer in my case)
3. Go to Applications >> WebSphere enterprise applications
4. Click on your application (MAXIMO in my case)
5. Click on Security role to user/group mapping
6. Check the checkbox for Role - maximouser (in my case)
7. Select the value as All Authenticated in Application's Realm from the Map special Subjects drop down menu 
   
8. Restart the Application Server

It should work now.
