I solved it with mod_perl:

<Perl>
     my $group = "users";
     my $output = `members $group`;
     chomp($output);
     my @members = split(/\s+/, $output);
     foreach ( @members ) {
       push @PerlConfig, qq|
<Directory /home/$_ >
      DAV On
      AuthName "webdav"
      AuthType Basic
      AuthBasicProvider external
      AuthExternal pwauth
      Require user $_
      AssignUserID $_ $_
      Options +Indexes
      AllowOverride all
</Directory> |;
}
</Perl>
