func CreateGrpcMiddlewareAuthFunction added in v0.9.4 

func CreateGrpcMiddlewareAuthFunction(authService AuthService) func(ctx context.Context) (context.Context, error)

func (*PrincipalPermissionChecker) UserHasPermission added in v0.4.52 

func (checker *PrincipalPermissionChecker) UserHasPermission(ctx context.Context, perm permission.Permission) bool

UserHasPermission returns true if the principal contained in the context has the given permission, which is determined by checking if any of the groups, scopes, or claims associated with the principal has that permission.

func (checker *PrincipalPermissionChecker) UserOwns(ctx context.Context, obj Owned) (owned bool, ownershipGroups []string)

UserOwns check if obj is owned by the principal contained in the context, or by a group of which the principal is a member. If obj is owned by a group of which the principal is a member, this method also returns the list of groups that own the object and that the principal is a member of. If obj is owned by the principal in the context, no groups are returned.

TODO Should we always return the groups (even if the principal owns obj directly)?
