Sendxmpp auth error with ejabberd (SOLVED)

05.2020 FreeBSD 12.1

• Problem: Sendxmpp cant connect to ejabber with DIGEST-MD5 mechanism
• Solution 1: force PLAIN auth:
  • file /usr/local/lib/perl5/site_perl/XML/Stream.pm line 2254:

my $sasl = Authen::SASL->new(mechanism=>join(" ",@{$mechanisms}),

change to

my $sasl = Authen::SASL->new(mechanism=>'PLAIN',

• Solution 2: Problem with DIGEST-MD5 is authzid field supplied in 1st responce, so we can just remove it:
  • file /usr/local/lib/perl5/site_perl/Authen/SASL/Perl/DIGEST_MD5.pm line 286:
    

comment out

  if (defined $authzid) {
    $response{authzid} = $authzid;
  }

• Solution 3: Problem with authzid field is the it have incorrect value (from ejabberd's view):
  

ejabberd takes only 2 possible values of authzid - empty (Solution 2) or username (without @domain), but perl Authen:SASL:Perl send 'username@domain' value. We can correct this:

• • file /usr/local/lib/perl5/site_perl/Authen/SASL/Perl/DIGEST_MD5.pm line 285:
    

  my $authzid = $self->_call('authname');

change to

  my $authzid = $self->_call('user');
