Keystone policy rule "identity:get_identity_providers" was ignored
Keystone policy rule "identity:get_identity_providers" was ignored ---
A policy rule in Keystone did not behave as intended leading to a less secure configuration than would be expected.
Affected Services / Software
OpenStack Identity Service (Keystone) versions through Mitaka, as well as Newton (<= 10.0.3), and Ocata (<= 11.0.3).
Deployments were unaffected by this problem if the default rule was changed or the "get_identity_providers" rule was manually changed to be "get_identity_provider" (singular) in keystone's `policy.json`.
A spelling mistake in the default policy configuration caused these rules to be ignored. As a result operators that attempted to restrict this API were unlikely to actually enforce it.
Update Keystone to a minimum version of 18.104.22.168b3. Additionally, this fix has been backported to Ocata (11.0.3) and Newton (10.0.3).
Fix any lingering rules: `identity:get_identity_providers` should be changed to `identity:get_identity_provider`.
