<p style='margin-top:0;margin-bottom:10px;'>I'm using Shibboleth 2.5.2 on Apache 2.4, on Ubuntu Server 13.10 64 bit.</p>
<p style='margin-top:0;margin-bottom:10px;'>When I have a directory with an .htaccess file like this:<br/>
AuthType Basic<br/>
AuthName "Private Area"<br/>
AuthUserFile .htpasswd<br/>
Require valid-user</p>
<p style='margin-top:0;margin-bottom:10px;'>It works fine when mod_shib is not enabled, but when mod_shib is enabled and ShibCompatValidUser On, and I try to get a directory listing, I get a 500 error and the following error message:<br/>
shib_auth_checker found no per-request structure</p>
<p style='margin-top:0;margin-bottom:10px;'>When it's a regular file I'm accessing, or the directory contains an index file, it works just fine.</p>
<p style='margin-top:0;margin-bottom:10px;'>I tried to hack the source code a bit and these are my observations:</p>
<ul class="alternate" type="square">
<li>Completely ripping out Shibboleth's valid-user handling code doesn't fix it, so it doesn't seem to have anything to do with that.</li>
<li>If after line 875 (if (!rc || !rc->sta)) I insert a check whether bCompatValidUser is enabled and return DECLINED, it works, but I have no idea whether this kind of fix is appropriate.</li>
<li>The error occurs because rc is NULL</li>
<li>I can always reproduce the error, on different servers, including a clean Ubuntu 13.10 64-bit install on a VM.</li>
</ul>
<p style='margin-top:0;margin-bottom:10px;'>For now, I'm using a workaround where I turn on ShibDisable by default, and only turn it off when it's actually necessary.</p>
