## Want

- Add a tab on the group (and user) view that lists application bindings / entitlements / mapped applications

## Ideas this came from

- [#16960 Add "Mapped Applications" tab to Group view & optional dashboard integration.](https://github.com/goauthentik/authentik/issues/16960) — Currently, we can see which applications have access to a group. I propose adding a tab within the group view that lists the applications mapped to that group.
- [#17265 See bindings/entitlements under group/user](https://github.com/goauthentik/authentik/issues/17265) — The ability to see what entitlement and binding a group or user has from the group and user overview. This way you can find permissions and access in two direct
- [#21440 Group bindings tab](https://github.com/goauthentik/authentik/issues/21440) — Is your feature request related to a problem? I'm always frustrated when figuring out all bindings by group I'd like authentik to see an “Group bindings” tab in

Start by locating the group and user views, then trace the existing application binding, entitlement, and mapped-application displays referenced in the issue. Done means both views have a tab listing the applications and access mappings for that group or user, with the relevant bindings or entitlements visible.
