When setting up client authentication for an OpenStack user (glance) and there is a small typo somewhere in the pool name variable... the glance import image fails with the following error:

glance image-create --name cirros --is-public=true --disk-format=qcow2 --container-format=bare < cirros-0.3.1-x86_64-disk.img
Request returned failure status.
500 Internal Server Error
Failed to upload image f46a2ca6-25af-40e9-9f23-7fd9d0315ad8
(HTTP 500)

looking at the /var/log/glance/api.log there is a error with Operation not permitted. See below snippet:

after spending few hours troubleshooting it turns out that I had a small typo in the caps after pool= there is a white space:
client.glance
key: AQDfb65VTo66BBAAe405rs4ejdLS3Vy2Yzkowg==
caps: [mon] allow r
caps: [osd] allow class-read object_prefix rbd_children, allow rwx pool= glance-images
