=head1 NAME

       smbldap-groupmod.pl - Modify a group

=head1 SYNOPSIS

       smbldap-groupmod.pl [-g gid [-o]] [-n group_name ] group

=head1 DESCRIPTION

       The smbldap-groupmod.pl command modifies the system account files to
       reflect the changes that are specified on the command line.
       The options which apply to the smbldap-groupmod command are

       -g gid The numerical value of the group's ID. This value must be
              unique, unless the -o option is used. The value must be non-
              negative. Any files which the old group ID is the file
              group ID must have the file group ID changed manually.

       -n group_name
              The name of the group will be changed from group to group_name.

       -m members
	      The members to be added to the group in comma-delimeted form.

       -x members
	      The members to be removed from the group in comma-delimted form.

=head1 EXAMPLES

       smbldap-groupmod.pl -g 253 development
	      This will change the GID of the 'development' group to '253'.

       smbldap-groupmod.pl -n Idiots Managers
	      This will change the name of the 'Managers' group to 'Idiots'.

       smbldap-groupmod.pl -m "jdoe,jsmith" "Domain Admins"
	      This will add 'jdoe' and 'jsmith' to the 'Domain Admins' group.

       smbldap-groupmod.pl -x "jdoe,jsmith" "Domain Admins"
	      This will remove 'jdoe' and 'jsmith' from the 'Domain Admins' group.
