Re: [keycloak-dev] [keycloak-gatekeeper] Add resource filter to allow specific users

Hi Stian, Thanks for your quick reply. In further researching the issue I’ve just found that there is already functionality in Gatekeeper that does exactly what I was trying to implement. The option `—match-claims` allows for specifying only a specific user that is allowed access in the following way (for my use-case): `—match-claims=‘preferred_username=someusername’`. Hope this helps anyone looking for this in the future.

By allowing a specific user there is no way to limit access in different tokens, which means that any token issued to the user will give access. This is very contradictory to the whole OAuth/OIDC paradigm where you have scoped tokens. Further, it's hard to manage access for individual users in such a way. Imagine the user should not have the access anymore. Now you have to update config for Gatekeeper instead of removing the role from the user. It is also not much overhead to add a role or a group for a user.
