+;******************************************************************************
+; File to define cifsd configuration parameters which are comparable with
+; samba's ones
+;
+; Supported [global] level parameters list:
+;      - server string
+;              This controls what string will show up in browse lists next
+;              to the machine name
+;      - workgroup
+;              This controls what workgroup your server will appear to be
+;              in when queried by clients
+;      - netbios name
+;              This sets the NetBIOS name by which a SMB server is known.
+;              By default it is the same as the first component of the host's
+;              DNS name. If a machine is a browse server or logon server this
+;              name (or the first component of the hosts DNS name) will be
+;              the name that these services are advertised under.
+;      - server min protocol
+;              This setting controls the minimum protocol version that the
+;              server will allow the client to use.
+;      - server max protocol
+;              The value of the parameter (a string) is the highest protocol
+;              level that will be supported by the server.
+;      - server signing
+;              This controls whether the client is allowed or required to use
+;              SMB1 and SMB2 signing. Possible values are default, auto,
+;              mandatory and disabled.
+;      - guest account
+;              This is a username which will be used for access to services
+;              which are specified as guest ok.
+;      - max active sessions
+;              This option allows the number of simultaneous connections to
+;              a service to be limited.
+;      - ipc timeout
+;              This option specifies the number of seconds server will wait
+;              for the userspace to reply to heartbeat frames. If user space
+;              is down for more than `ipc timeout` seconds the server will
+;              reset itself - close all sessions and all TCP connections.
+;      - restrict anonymous
+;              The setting of this parameter determines whether user and
+;              group list information is returned for an anonymous connection.
+;      - map to guest
+;              This parameter can take four different values, which tell cifsd
+;              what to do with user login requests.(bad user
+;      - bind interfaces only
+;              This global parameter allows the cifsd admin to limit what
+;              interfaces on a machine will serve SMB requests.
+;      - interfaces
+;              This option allows you to override the default network
+;              interfaces list that cifsd will use for browsing. The option
+;              takes only list of interface name.
+;      - deadtime
+;              The value of the parameter (a decimal integer) represents
+;              the number of minutes of inactivity before a connection is
+;              considered dead, and it is disconnected. The deadtime only
+;              takes effect if the number of open files is zero.
+;      - root directory
+;              Sets up a root (base) directory for all shares. In some
+;              sense it's equal to chroot(). When this option set all shares'
+;               paths become relative to root directory, IOW the file name
+;               lookup resolves '/root directory/share path/file path' path.
+;
+; Supported [share] level parameters list:
+;      - comment
+;              comment string to associate with the new share
+;      - path
+;              This parameter specifies a directory to which the user of the
+;              service is to be given access.
+;      - guest ok
+;              If this parameter is yes for a service, then no password is
+;              required to connect to the service.
+;      - read only
+;              If this parameter is yes, then users of a service may not
+;              create or modify files in the service's directory.
+;      - browseable
+;              This controls whether this share is seen in the list of
+;              available shares in a net view and in the browse list.
+;      - write ok
+;      - writeable
+;              Inverted synonym for read only.
+;      - store dos attributes
+;              If this parameter is set cifsd attempts to first read DOS
+;              attributes (SYSTEM, HIDDEN, ARCHIVE or READ-ONLY) from a
+;              filesystem extended attribute, before mapping DOS attributes
+;              to UNIX permission bits (such as occurs with map hidden and
+;              map readonly).
+;      - oplocks
+;              This boolean option tells cifsd whether to issue oplocks
+;              (opportunistic locks) to file open requests on this share.
+;      - create mask
+;              When a file is created, the necessary permissions are calculated
+;              according to the mapping from DOS modes to UNIX permissions, and
+;              the resulting UNIX mode is then bit-wise 'AND'ed with this
+;              parameter.
+;      - directory mask
+;              This parameter is the octal modes which are used when converting
+;              DOS modes to UNIX modes when creating UNIX directories.
+;      - force group
+;              This specifies a UNIX group name that will be assigned as
+;              the default primary group for all users connecting to this
+;              service.
+;      - force user
+;              This specifies a UNIX user name that will be assigned as
+;              the default user for all users connecting to this service.
+;      - hide dot files
+;              This is a boolean parameter that controls whether files starting
+;              with a dot appear as hidden files.
+;      - hosts allow
+;              This parameter is a comma, space, or tab delimited set of hosts
