hello, 
I'm trying to install manila in my openstack cloud but having problem with "Authorizing the driver to communicate with Ceph" 

1 -> i have created a configmap with these confs and mounted it on manila-share pod

[client.manila]
client mount uid = 0
client mount gid = 0
log file = /opt/stack/logs/ceph-client.manila.log
admin socket = /opt/stack/status/stack/ceph-$name.$pid.asok
keyring = /etc/ceph/manila.keyring

2 -> then i have created a secret with client.manila keyring and attached it to the manila-share pod at 

keyring = /etc/ceph/manila.keyring

3 -> inside manila-share pod i see the logs
