Hi Graham, using smaller junks of data solves the problem! Thank you very much! It solved the problem on both AD and OpenLDAP and sending smaller junks of data seems generally to be a good idea.
Cheers, Swen -----Ursprüngliche Nachricht----- Von: Graham Barr [mailto:[EMAIL PROTECTED] Gesendet: Samstag, 2.

I cannot reproduce the problem myself, so I cannot try these tests. 1) Does it hang in syswrite(), we can check this by adding warn "HERE" after the syswrite on line 773 of LDAP.pm If it is in syswrite() maybe IO::Socket::SSL does not like data sent that size. We could try sending smaller chunks by changing the syswrite() line to be (warning - untested) my $to_send = \( $msg->pdu ); my $offset = 0; while($offset < length($$to_send)) { my $n = syswrite($socket, substr($$to_send, $offset, 15000), 15000) or return _error($ldap, $mesg, LDAP_LOCAL_ERROR,"$!"); $offset += $n; } Can someone who sees the problem please try this.
