How to edit User Profile info in RTC When the User name is read only?
One answer
When you are at the user profile page, do you see this message near the top of the page?
Because this server is connected to an external user registry, some user details including User ID, E-Mail Address, and Repository Permissions are read-only. To modify these read-only details, you must make the changes in the external user registry.If so, as indicated, you need to ask the administrator of the external user registry (LDAP, WebSphere federated user registry, and etc) to change it.
With RTC 5.0.2, it is only possible to change the name there when using the builtin Tomcat User Management.
