Hi there,
Versions:
Windows XP SP3 32-bit
CYGWIN_NT-5.1 2.5.1(0.297/5/3) 2016-04-21 22:12 i686 Cygwin
This is perl 5, version 22, subversion 2 (v5.22.2) built for cygwin-thread-multi-64int
perl-Authen-SASL-2.16-2
perl-Authen-SASL-XS-1.00-1
When I've installed perl-Authen-SASL-XS package required by perl-Authen-SASL
my script can't auth() on SMTP server. Debug log:

No any diagnostics from Authen::SASL.
If I've uninstalled perl-Authen-SASL-XS all work. Debug log (base64'd user name

Authen::SASL POD says:
The framework allows different implementations of the connection class to be
plugged in...
By default the order in which these plugins are selected is
Authen::SASL::XS, Authen::SASL::Cyrus and then Authen::SASL::Perl.
If you want to change it or want to specifically use one implementation only
simply do
use Authen::SASL qw(Perl);
but I don't want to change Net::SMTP module that uses that code (uses default
Authen::SASL plugin):
/usr/lib/perl5/5.22/Net/SMTP.pm (160):
eval {
require MIME::Base64;
require Authen::SASL;
} or $self->set_status(500, ["Need MIME::Base64 and Authen::SASL todo auth"]), return 0;
Problem? Is Authen::SASL::XS so required to install with Authen::SASL if
Authen::SASL works fine without it? I'm not expert in Perl, but I think that
module's code says "use what you found":
/usr/lib/perl5/vendor_perl/5.22/Authen/SASL.pm (13):
@Plugins = qw(
Authen::SASL::XS
Authen::SASL::Cyrus
Authen::SASL::Perl
);
sub import {
shift;
return unless @_;
local $SIG{__DIE__};
@Plugins = grep { /^[:\w]+$/ and eval "require $_" } map { /::/ ? $_ : "Authen::SASL::$_" } @_
or croak "no valid Authen::SASL plugins found";
}
Google found couple pages for me where advised to remove Authen::SASL::XS.
https://foswiki.org/Support/Faq69
Authen::SASL comes with a pure perl version of the mechanism, and can also
use some optional implementations: Authen::SASL::XS or Authen::SASL:Cyrus.
If either the XS or Cyrus modules are installed, try removing them.
https://rtcpan.develooper.com/Public/Bug/Display.html?id=100235
$client is now set but $client->mechanism returns undef. Therefore
$mechanisms =~ s/\b\Q$failed_mechanism\E\b//; does not change $mechanisms at
all and the loop tries the same $mechanisms over and over again.
Uninstalling Authen::SASL::XS is as a workaround for us since with
Authen::SASL::Perl everything seems to work just fine.
They says about "Error: Use of uninitialized value $_..." and unknown
authentication mechanism but about removing Authen::SMTP::XS too.
Thanks.
Sorry for the verbosity.
