When viewing clients in the OAuth manager you are unable to see all of the registered clients even when assigned an administrator role on the Gateway.
By default there are only 3 user names that are considered as administrators in OAuth.
These are admin, pmadmin and administrator. User role assignment will not affect these permissions and any other accounts must be explicitly set in policy to be administrators.
Otherwise you will be restricted to only seeing clients that your ID has registered.
