Ceph

Hi all,

I want to integrate ceph and glance, and enable RBD as glance storage backend. Request commited by defaulf user 'admin' is OK, and I follow the blog [http://www.sebastien-han.fr/blog/2012/06/10/introducing-ceph-to-openstack/] to add new user 'glance' to commit request, it don't work(e.g # glance add ...). My ceph auth list is:
mds.1
key: AQBzEK9QiDEwDBAAgFFrWVOWSde5E7mTL3xmmA==
caps: [mds] allow
caps: [mon] allow rwx
caps: [osd] allow *
osd.2
key: AQBxEK9QQGmqLhAASbjPqHvUBlptI5+NRWefhw==
caps: [mon] allow rwx
caps: [osd] allow *
osd.3
key: AQBzEK9QkGn5BxAAP6uIeuZs1kAOJDkYAPoCvw==
caps: [mon] allow rwx
caps: [osd] allow *
client.admin
key: AQBzEK9QMKNLDhAAKMV6iJI8BcDmuCjCQTzHRw==
caps: [mds] allow
caps: [mon] allow *
caps: [osd] allow *
client.glance
key: AQAwNbRQMF3wLBAAAMKQVZBwzM+uTpa239juPA==
caps: [mon] allow r
caps: [osd] allow rwx pool=images

BTW, My test pool named 'images'.

I then go to debug by calling rbd command '# rbd -n client.glance -p images ls', it report:

I also checked the mon's log, the error is just like below:
cephx server client.glance: unexpected key: req.key=f4e0b6ab42d5d38f expected_key=7f2a426218e7788f

Attachement is my glance-api.conf.
If you anyone have met this issue or can give me some suggestion, I will feel grateful!
