+fixes:
+  - |
+    Removed ``rule`` kwarg from ``rbac_rule_validation`` decorator for identity
+    v2 admin tests, because the identity v2 admin API does not do policy
+    enforcement, and instead checks whether the request object has
+    ``context_is_admin``.
+other:
+  - |
+    Updated the class names for identity v2 tests to include the "Admin"
+    substring, to convey the fact that these tests are only intended
+    to test the v2 admin API, not the v2 API.
