=head1 SYNOPSIS
smbldap-groupmod.pl [-g gid [-o]] [-n group_name ] group

unique, unless the -o option is used. The value must be non-

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"
