Hello Howard I've red this manpage quite a lot. Also trying to find somewhere documentations about overlay interfaces, but without any success I've also red the code. I don't understand how to say doit.. Here is my perl code, doing nothing.. #!/usr/bin/perl use IO::Socket::UNIX; my $socket_path = '/tmp/mysocket'; unlink $socket_path if -e $socket_path; my $socket = IO::Socket::UNIX->new( Local => $socket_path, Type => SOCK_STREAM, # Type => SOCK_DGRAM, Listen => SOMAXCONN, ); die "Can't create socket: $!" unless $socket; while (1) { next unless my $connection = $socket->accept; if (fork() == 0) { $connection->autoflush(1); while (<$connection>) { #chomp($line); print ; next if /^ADD$/; next if /^msgid:/; next if /^suffix:/; print $connection $_; last if /^$/; } print $connection "CONTINUE\n"; exit; } } And here is a BUG, in back-sock/result.c It goes here only once at the end of the ldif, but never after.. /* line marked the end of an entry or result */ if ( *line == '\n' ) { Debug( LDAP_DEBUG_ANY, "TRACE1 \n", 0, 0, 0 ); if ( strncasecmp( buf, "RESULT", 6 ) == 0 ) { break; } Debug( LDAP_DEBUG_ANY, "TRACE2 buf=%s\n",buf, 0, 0 ); if ( strncasecmp( buf, "CONTINUE", 8 ) == 0 ) { Debug( LDAP_DEBUG_ANY, "TRACE3\n", 0, 0, 0 ); struct sockinfo *si = (struct sockinfo *) op->o_bd->be_private; /* Only valid when operating as an overlay! */ assert( si->si_ops != 0 ); rs->sr_err = SLAP_CB_CONTINUE; goto skip; } So I just put if ( strncasecmp( buf, "CONTINUE", 8 ) == 0 ) outside of if ( *line == '\n' ) { and it works.. I am no more a C specialist (1985 last time) so I don't know how to patch Hope this helps other people, or if I'm wrong please correct me Thanks Dom 2015-06-23 18:22 GMT+02:00 Howard Chu <hyc(a)symas.com&gt;:

Hum, my version is 2.4.40, so that's the last version. Is there a mistake somewhere? Thanks Dom 2015-06-24 21:33 GMT+02:00 Howard Chu <hyc(a)symas.com&gt;:

But from the second time until forever the data cannot be fully transmitted and Python raises exception error: [Errno 32] Broken pipe. Can anybody confirm what exactly should be returned in this case? [ ] CONTINUE [ ] CONTINUE\n [ ] CONTINUE\n\n Ciao, Michael.

Maybe I'm overlooking something in slapd-sock(5) but I cannot find a description what to the external listener should return in case of RESULT and ENTRY. Ciao, Michael.
