<neutron_lib.constants.Sentinel object at 0x7f239bb3e410> permissions error

Issue

• We see an issue where a heat stack fails due to a permissions issue. A similar heat stack in another location where the user has the exact same permissions (member role) fails. If we give them elevated permissions, it works. The error message is:

CREATE_FAILED  Resource CREATE failed: Forbidden: resources.stack_name.resources.resource_name: ((rule: create_port and rule: create_port: allowed_address_pairs) and rule: create_port: fixed_ips) on {'binding: host_id': <neutron_lib.constants.Sentinel object at 0x7f239bb3e410>, u'name
