NEW: chasing referrals

[Roland S. <rol...@ep...>]

Hi all,

I've got a problem understanding the information posted earlier on this
mailing list:

     Not yet. Currently you have to follow them yourself. You can
     get them with

       $mesg = $ldap->search( ... );
       @referrals = $mesg->referrals;

     Graham.
----- end

(We are using Net::LDAP 0.22 and OpenLDAP 1.2.11)

It seems that my configuration doesn't return any referrals. I have
configured two servers, one holding o=epigenomics, the other on
c=us,o=epigenomics. Via PHP and ldapsearch tools, the inserted referrals
even seem to transparently redirect the client to the second server when
accessing/searching the c=us,epigenomics substructure. But with my
Net::LDAP code:

--- begin
$ldap = Net::LDAP->new("wilson"); # connect to root server
$ldap->bind;
$mesg = $ldap->search( base => "o=epigenomics",
                       filter => '(&(cn=*)(objectclass=*))',
                       deref => 3,
                       );
@referrals = $mesg->referrals;
foreach $ref (@referrals) {
  print "Referral: ",$ref,"\n";
}

print "Return code: ",$mesg->code,"\n";
print "Error message: \"",$mesg->error,"\"\n";
$n = $mesg->all_entries;
print "Number of Entries: ".$n."\n";

foreach $entry ($mesg->entries) {
  print "dn: ",$entry->dn,"\n";
}
--- end
 
I don't get any referrals (the response is:)

--- begin
Return code: 9
Error message: "Referral:
ldap://deledda/c=us,o=epigenomics"
Number of Entries: 2
dn: cn=admin,o=epigenomics
dn: cn=updated,o=epigenomics
--- end

(There should be more users. ldapsearch and PHP functions are able to
provide them.)

Thanks for your ideas!

bye,
  Roland
