Hi ,i take the followng steps , fail to mount,too.
## save auth secret to a file:
$cauthtool --print-key /etc/ceph/keyring.bin > /etc/ceph/secret
chmod 600 /etc/ceph/secret
## future ,support,read a secret from a file
$ mount -t ceph 172.16.50.10:6789:/foo /mnt/ceph
-o name=admin,secretfile=secret
but ,the following steps ,mount ceph is successful.
# enable cephx, add a user and secret
$ mount -t ceph -o name=admin,secret=<secret>
1.2.3.4:/ /mnt/ceph
$ mount -t ceph 172.16.50.10:6791:/foo /mnt/ceph
-o name=admin,secret=‘AQArWtdMiI1uDRAAVbNRMeiwsjK+DEMeB7ewLg==’
# cauthtool --list keyring.bin
client.admin
key: AQArWtdMiI1uDRAAVbNRMeiwsjK+DEMeB7ewLg==
