[keycloak-user] Unable to create user with roles using Rest API

[Hylton Peimer]

I have created a new Realm and added a role: "DOCTORS".

POST to /admin/realms/{realm}/users

With the following JSON:
 {"realmRoles":["DOCTORS"],"enabled":"true","username":"drhp"}

This invocation creates the user, but the "DOCTORS" role is not assigned.

The rest call is using a bearer token obtained from an administrative user
in the master realm.
