1. Problem Description:
Hi all,
When I try to do a simple anonymous LDAP bind using Net::LDAP
(perl-ldap-0.3202):
my $ldap = Net::LDAP->new('myldapserver', port => '389') or die
"Unable to connect: $!\n";
I get a "Connection to host ... is broken".
Here is the output of the error_log file:
[Mon Oct 11 15:23:03 2004] [debug] util_ldap.c(1432): INIT global
mutex /tmp/file2XTVzj in child 12556

I am running Linux Debian 3.0 rev2 (Woody), kernel 2.4.27.
Many thanks.

3. This is the core dump trace: (if you get a core dump):
I've been reading the following doc on how to get a core dump file:
http://perl.apache.org/docs/2.0/devel/debug/c.html#Analyzing_Dumped_Core_Files
I followed the section: Getting the core File Dumped
Then I run Apache as described: /usr/local/apache2/bin/httpd
-DONE_PROCESS -DNO_DETACH
Issue a request. But I get a Segmentation Fault without core dump ...
