Hi team,

Hope you are doing well. We have NTLM Sharepoint application configured in
our application. The library we are using to support the authentication
operation/feature is *LWP::Authen::Ntlm and Net::SSL*. The authentication
flow is similar to what is posted in the page=E2=80=99s
<https://metacpan.org/pod/LWP::Authen::Ntlm> synopsis. It was working fine
with apache2-2.4.51(without tls1.3) and *openssl-1.0.2p*.

But recently we upgraded the apache2 library to support tls1.3(with
*openssl-1.1.1d*). After this upgrade, the app is not able to make a socket
connection to the sharepoint server. When debugged further - it wasn't able
to create an ssl-socket using *Crypt::SSLeay::Conn->new *in
*Net::SSL(v2.85)* module.

Could you please let us know what might be the possible reasons for this
issue and what are the possible ways to resolve this issue?

Apache2 mod-perl : *apache2-mod_perl-2.0.8-13.5.1.x86_64*
LWP based modules :
*perl-libwww-perl-6.05, perl-LWP-MediaTypes-6.02,
perl-LWP-Protocol-https-6.04, perl-IO-Socket-SSL-2.052-4.3.1,
perl-Crypt-SSLeay-0.64-3.57, perl-NTLM-1.09-1.1,
perl-Net-HTTP-6.06-5.2, perl-Net-SSLeay-1.64-3.2.*


Thanks,
N G Hemanth Kumar
