My self Hemant Sonawane. Recently I am working on openstack and I am getting some strange error when I installed openstack dashboard and tried to edit the visibility of images and update their metadata it dosent work I get Forbidden : Redirecting to login and Unable to edit the image custom properties such errors.

I also tried to see the glance-api logs and found this 

Is there any glance policy in horizon?  that might cause this error I think.

The detail log file attached for your ready reference. So please look into my concern and let me know if there is any solution to resolve my issue. 

Thanks and Regards,
