I am trying to connect to an LDAP server using the Net::LDAPS module. I am passing the right username, password and capath to it. The same code with all the modules in the same version works on one of my other machines. But on this particular machine I see this error.
The sample code I am working with :
my $ad_host = 'XYZ';
my $ad_port = 636;
my $ad_user = 'ABC';
my $ad_pass = '****';
my $ca_path = '<path to ca cert>';
my $ldap = Net::LDAPS->new(
$ad_host,
port => $ad_port,
verify => 'require',
capath => $ca_path
);
Is it a known bug in the LDAPS module? Or am I missing out something apparent.

Versions of the modules I am using :
...:~/test_perl$ perlmodver Net::LDAPS 0.05
...:~/test_perl$ perlmodver Net::LDAP 0.39
...:~/test_perl$ perlmodver IO::Socket::SSL 1.18
This issue is resolved.
There are 2 ways to solve this :
Bypass the verification (Not recommended)
If you are using the "verify" attribute like the one in my code, you just have to comment it out. It will bypass the cert verification.
Add a soft link to the certificates
Maybe it is a behavior specific to trusty, because on lucid it was working fine. So, you need to create a soft link to all your pem files and place it in the CA Path. You can do this by running
ln -s cacert.pem `openssl x509 -hash -noout < cacert.pem`.0
