  • In ABP, /api/abp/application-configuration returns auth.grantedPolicies for the current user. A permission can be true there even if there is no row in AbpPermissionGrants.

    • Because the permission system is not “DB row = granted”. The DB table stores overrides (grant/prohibit) for a provider (Role/User/Client). If a permission is granted by some other mechanism, you may not see a direct row for the specific permission/provider you are checking.
    • Common reasons a permission shows as true without a matching row:
      1. Granted by role (or another provider): the grant may exist for the role (or another provider), not for the user. So you won’t find a row when filtering by the user’s provider key.
      2. Default-granted permissions: some permissions are defined to be granted by default (or effectively always granted for certain users like host admin depending on module/permission configuration). In such cases, ABP can return true without needing a DB record.
      3. You are looking at the wrong tenant/provider key: AbpPermissionGrants is tenant-scoped. If you check the table without matching TenantId (and correct ProviderName/ProviderKey), you can miss the record that actually caused the grant.
      4. Stale client-side application configuration: Angular reads permissions from the application-configuration response and caches it in the client. If permissions changed, the UI can keep showing old values until a full refresh.

  • Fix it in a definitive way (server + Angular):

    1. Confirm what provider grants it
       • Use the Permission Management UI to inspect the permission for the user/role and see whether it is granted via role or another provider.
       • In code, prefer PermissionAppService.GetAsync(providerName, providerKey) (Permission Management Module) which returns details including “granted providers” (useful for diagnosing why it’s true).
    2. Verify the correct tenant
       • When you query AbpPermissionGrants, filter by the correct TenantId (and correct ProviderName/ProviderKey).
    3. If your intention is “not granted unless explicitly granted”
       • Ensure the permission is not configured as granted by default in its definition.
       • Explicitly prohibit it for the relevant provider (role/user) so ABP persists a IsGranted = false row (a prohibition). That guarantees the permission resolves to false even if it might otherwise be granted.
    4. Refresh Angular’s permission map
       • After changing permission grants, do a full page reload so Angular re-fetches /api/abp/application-configuration.
       • If you update permissions from within the app, reset the current application configuration cache on the client side (ABP provides mechanisms for cache reset in some UIs; otherwise reload is the simplest).

  • Angular button show/hide best practice:

    • Use ABP Angular’s PermissionService.getGrantedPolicy(...) (or getGrantedPolicy$) and ensure you are checking the exact permission name.
    • Be careful: an empty string permission key returns true in ABP Angular permission selectors, which can make it look like “everything is true” if the key you pass is accidentally empty.

  hi

  Can you clear the Redis cache if you are using it?

  What is your current user info?

  Can you share data in the AbpPermissionGrants table?

  Maybe your current user's role has all permissions.

  Thanks.

  Hi,

  We are not using Redis cache. Our current role does not have all the permission. Even though we are creating new tenant/user and providing limited access, the RBAC policies are not working.

  Scenario:

  1. Update the permission by removing some permissions from the UI.
  2. User has been untagged from the permission in both backend and front end.
  3. User is logging out and log in again.
  4. After successfully login by the user, we can see the same user has been tagged with removed permissions from open configuration API response.

  Please let me know if you need more deatils

  • What you’re seeing is consistent with client-side permission caching in ABP Angular / application-configuration usage, not with AbpPermissionGrants being “wrong”.
  • In ABP, changing role/user permissions is effective on the server immediately, but the UI may continue to use the previous grantedPolicies until the client refreshes/reloads its cached application configuration.

  Do this to fix your scenario (RBAC not reflected after you remove permissions):

  1. Force the Angular client to re-load application configuration after login/logout and after permission changes

     • Ensure you are not keeping the old ApplicationConfigurationDto in memory across sessions (SPA can do this).
     • After logout, do a hard reload (or clear the cached config state your app keeps).
     • After changing permissions from the UI, also reload the page (or explicitly re-fetch /api/abp/application-configuration) for the affected user to refresh grantedPolicies.

  2. Verify you are not accidentally checking an empty/incorrect permission key in Angular

     • If your permission name expression becomes ''/null due to a bug, many UI checks will behave unexpectedly and may look like “everything is granted”.
     • Confirm the exact permission string you use in *abpPermission, PermissionService.getGrantedPolicy(...), etc.

  3. Double-check tenant context when reading grants

     • AbpPermissionGrants is tenant-scoped. If you check grants with the wrong TenantId or wrong provider key/name, you can think it “doesn’t exist” while it actually exists for another tenant/provider.

  4. Confirm it’s not granted via another provider

     • Even if you removed a permission from a user, it can still be granted via a role (or another provider). In the Permission Management UI, the “(R)” indicator shows role-originated grants.

  If you implement #1 (refresh/re-fetch application configuration) your “removed permissions still come back in open configuration response” symptom should stop, because the frontend will stop using the stale grantedPolicies.
