Mount with only user_principal (should fail)

Is 'lustre' the correct filesystem name?
Are the mount options correct?
Check the syslog for more info.
Mount client oleg335-client.virtnet: mount -t lustre -o user_xattr,flock,user_principal 192.168.203.135@tcp:/lustre /mnt/lustre
Mount failed as expected with only -o user_principal
