<div class="WordSection1">
<p class="MsoNormal">Hello again,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As you know, yesterday was an exciting day for me, getting my first Shibboleth project running in my dev environment. My users are held in a Microsoft Active Directory (2008 R2 DC’s, 2003 functional level). I was aware that the default
search base is CN=Users so I had put my test user there.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Today I went to expand that and I’ve run into issues. I’d like to be able to search from the root of my AD dc=ad,dc=loyalistcollege,dc=ca , so I edited my attribute-resolver.xml file on my IdP, restarted the service, and tested. I found
that it wasn’t working – users NOT in the cn=users container were rejected by Shib, and my test user in the cn=users container was authenticated by Shib but rejected by the resource I’m protecting (remote_user not set)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I checked the documentation I see the common cause seems to revolve around refers. The docs say that I need to set <LDAPProperty name="java.naming.referral" value="follow"/> , as it is ‘ignore’ by default. I think that’s actually old
information because I can verify that in my instance it was set to ‘follow’ by default.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The other fix is to search a GC instead – which is not a problem for me (“horus” is a GC). I changed my ldapURL to use port 3268 (plain old) but I’m still getting the same results. If I move a user into the cn=users container they work,
but if they aren’t there, they won’t authenticate.<o:p></o:p></p>

<p class="MsoNormal">Any thoughts? I also read that I could stack multiple searches, which would also work for me ( I only have 3 or 4 OUs where users are) so I tried changing the base path to a specific OU where a user is, but I was also unable to authenticate.
