Re: [keycloak-dev] A newly added Hardcoded Role mapper ignores users that have already logged in before

Hi, That is an interesting point. I checked some mappers: - AttributeToRoleMapper handles the update like the import with the exception that in case of an update, the role is deleted if the attribute is no longer present (I call this for now inverted logic). - ClaimToRoleMapper and ExternalKeycloakRoleToRoleMapper handle an update with the inverted logic only – so they don’t set but only delete the role. - HardcodeRoleMapper fully ignores updates whereas it could at least do it the same way as AttributeToRoleMapper. - UserAttributeMapper is even more complex… So the currently used IdentityProviderMapper implementations are very inconsistent and hopefully documented and understood well for and by the end users.

All I am saying is that it will become a breaking change to globally define this behavior as there are nowadays several, conflicting modes implemented. Due to that I would like to emphasize that the flag introduction (“handleUpdateToo”) still seems as the solution with the lowest friction.

We need to make sure there is a consistent approach throughout. We probably don't have consistent and predictable behaviour today, but I would rather not make it worse by introducing random config options on mappers. Main question is if this should be controlled on individual mappers or if it should mainly be a config on the identity provider. Having the config on the identity provider would make more sense as it would be simpler to configure and it would avoid corner cases. There's probably at least 3 different modes for identity brokering that should be supported: 1) Import only - User is only imported if it doesn't exist. If user already exists nothing is updated. 2) Sync - Allow changes to the user within Keycloak, but also sync changes from external IdP 3) External - Do not allow any changes to the user within Keycloak as the user should be fully managed from the external IdP Option 1 is trivial. Option 2 can be very complicated. Take the example of the hardcoded role for instance. User first logs in, the role is added. An admin then removes the role from the user. User logs in again and the role is re-added. Same example can be applied to last name for instance. User logs in. 6 months later the user changes the last name in Keycloak account console, but then next day when they re-login the last name is changed back. Option 3 is relatively trivial, but would need some tweaks within Keycloak. A user that is fully externally managed should not be able to use Keycloak account console and should be view-only in the admin console.
