Usage: vault auth-enable [options] type

  Enable a new auth provider.

  This command enables a new auth provider. An auth provider is responsible
  for authenticating a user and assigning them policies with which they can
  access Vault.

General Options:
` + meta.GeneralOptionsUsage() + `
Auth Enable Options:

  -description=<desc>     Human-friendly description of the purpose of the
                          auth provider. This shows up in the auth -methods command.

  -path=<path>            Mount point for the auth provider. This defaults
                          to the type of the mount. This will make the auth
                          provider available at "/auth/<path>"

  -plugin-name            Name of the auth plugin to use based from the name 
                          in the plugin catalog.

  -local                  Mark the mount as a local mount. Local mounts
                          are not replicated nor (if a secondary)
                          removed by replication.
