Migration Tools: possible modification ? Re: dn and search on special caracters (+,;..)

[Jehan PROCACCIA <jehan.procaccia@int-evry.fr>]

You're right, I just need to escape + signs in the DN but not in the cn
attribute.
I've inserted code in migation tools scripts to do this automatically
(escaping + signs, example for whois++ service en TP++ protocol):

Here's what I've done:

migrate_protocols.pl

sub dump_protocol
{
        local($HANDLE, $name, $number, @aliases) = @_;
        $namedn=$name;
        if ($namedn =~ /\+/)
                {$namedn =~ s/\+/\\+/g;}

        print $HANDLE "dn: cn=$namedn,$NAMINGCONTEXT\n";


migrate_services.pl

        $servicenamedn=$servicename;
        if ($servicenamedn =~ /\+/)
                {
                $servicenamedn =~ s/\+/\\+/g;}

        print $HANDLE "dn:
cn=$servicenamedn+ipServiceProtocol=$proto,$NAMINGCONTEXT\n";


hope this would help others.

Thanks.
