Perhaps for those where it doesn't make sense to have an option it should display the sync-mode, but in non-editable mode? It allows to specify how should look username of the Keycloak user, which was registered through this Idp. Updating of username of already existing Keycloak user is not yet supported by this mapper. We can eventually add support for it during this work, but question is what should be default mode in this mapper? For example if updating usernames is disabled for the realm and you have IDP with value "owner", you probably don't want that UsernameTemplateMapper will inherit value "owner", because administrator doesn't expect usernames of existing user to be updated.

I think it would be nice to be able to show that a role/group mapping is managed externally, but I agree it's not the top priority. > Regarding User Profile SPI, I can imagine that it will be nice to have > the ability to automatically update the metadata/requirements based on some > events?

Right now I've not really covered this part in the user profile design as I haven't really thought it through. I'm kinda thinking about 2 options. First 1 where attributes can have different config based on the source, and another where you define different user profiles. The latter is probably simpler and cleaner. Let's move further discussion on this part elsewhere though. Both options are fine. But will be good to have it automatically added somehow. For example when administrator creates read-only LDAP provider, then in 95% cases, he also wants that LDAP users have all profile fields read-only in account management. So it can be nice if administrator doesn't need to manually create UserProfile for LDAP users as another required step. Where is better place to discuss? In the keycloak-dev thread you mentioned design about user profile design document?
