Hello,<div><br></div><div>I have setup otrs 3.0.5 with single sign on based on apache and mod_cas.</div><div><br></div><div>As this could be a problem when having different authentication scenarios for agents and customers, I have tried to setup a CAS auth module by copy/pasting code snippets here and there (I don&#39;t know perl...). I think I&#39;m almost there but I have an annoying bug I&#39;m asking help for now.</div>
<div><br></div><div>I have created a CAS.pm file in  /opt/otrs/Kernel/System/CustomerAuth</div><div><br></div><div>====</div><div><div>use CGI;</div><div>use AuthCAS;</div><div>use CGI;</div><div>use CGI::Carp qw( fatalsToBrowser );</div>
</div><div><br></div><div>...</div><div><br></div><div><div>sub Auth {</div><div>    my ( $Self, %Param ) = @_;</div><div><br></div><div>    my $cas = new AuthCAS(casUrl =&gt; &#39;<a href="https://sso.paris.iufm.fr/cas&#39;">https://sso.paris.iufm.fr/cas&#39;</a>);</div>
<div>    my $app_url = &#39;<a href="http://support.paris.iufm.fr/otrs/customer.pl">http://support.paris.iufm.fr/otrs/customer.pl</a>&#39;;</div><div><br></div><div>    unless ($ENV{QUERY_STRING} =~ /ticket=/) {</div><div>
    ###</div><div>    ### Redirect the User for login at CAS</div><div>    ###</div><div>      my $login_url = $cas-&gt;getServerLoginURL($app_url);</div><div>      printf &quot;Location: $login_url\n\n&quot;;</div><div>      exit 0;</div>
<div>    }</div><div><br></div><div>    $ENV{QUERY_STRING} =~ /ticket=([^&amp;]+)/; my $ST = $1;</div><div>    my $User = $cas-&gt;validateST($app_url, $ST);</div><div>    # return user</div><div>    return $User;</div><div>
}</div></div><div>============</div><div><br></div><div>The problem is with the line &quot;unless ($ENV{QUERY_STRING} =~ /ticket=/) {&quot;.</div><div>It seems the $ENV{QUERY_STRING} is empty (not tested but I end in an infinite loop, due to falling in this condition evrytime)</div>
<div><br></div><div>Would somebody have an idea about how to fix this check ?</div><div><br></div><div>Regards,</div><div><br></div><div>-- <br>Mikael Kermorgant<br>
