Hi Kristy,

Have you try the [] or @ rule as mentioned here?

https://github.com/openstack/keystone/blob/master/keystone/openstack/common/
policy.py#L71

 Subject: [openstack-dev] [keystone] Configuring protected API functions
 to allow public access
 
 Hi All,
 
 Correct me if I am wrong but I don't think you can configure the
 Keystone policy.json to allow public access to an API function, as far
 as I can tell you can allow access to any authenticated user regardless
 of role assignments but not public access.
 
 My use case is a client which allows users to query for a list of
 supported identity providers / protocols so that the user can then
 select which provider to authenticate with - as the user is
 unauthenticated at the time of the query the request needs to allow
 public access to the 'List Identity Providers' API function.
 
 I can remove the protected decorator from the required functions but
 this is a nasty hack.
 
 I suggest that it should be possible to configure this kind of access
 rule on a deployment by deployment basis and I was just hoping to get
 some thoughts on this.
 
 Many thanks,
 Kristy

That still requires valid authentication though, just not any specific
authorization. I don't think we have a way to express truly public
resources in oslo.policy.
