The OpenStack Manila CSI Driver Operator does not document how to define subnet/ip restrictions, to limit which pods can mount the Shares (PVs).

All versions where the Manila CSI driver operator documentation exists.

Always.

    1. In the OpenStack Manila CSI driver operator documentation [1], search for instructions on how to limit which pods can mount the shares based on their IPs/Subnets, using the `nfs-shareClient` [2] storage class parameter.

The documentation doesn't have any instructions on how to limit IPs or Subnets that can mount the Manila share/PV and the default Manila access rule is too permissive (0.0.0.0/0).

There are instructions on how to configure the access rules details.
