Comment 1 for bug 1700138

According to gouthamr,

> OP assigned a security service "manually" - i.e, they began with a NFS share server, and configured cifs directly on the backend
> manila doesn't know about this security service, and the driver fails to perform cleanup
> seems legit to me to call it a feature and not a bug :)
 > i.e, if someone configures something on the backend, manila fails to delete it - and that sounds appropriate

I'll confirm this behavior and mark it as Invalid.
