<p class="MsoNormal">I have a KDC set up on a Linux virtual host, known as ldap.abc, which has a<o:p></o:p></p>

<p class="MsoNormal">also copied over the /etc/krb5.conf file from a Linux host that is able to<o:p></o:p></p>
<p class="MsoNormal">contact it. It contains the following:<o:p></o:p></p>

<p class="MsoNormal">fails.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is this something that’s even possible to do? Any pointers on where I should go<o:p></o:p></p>
<p class="MsoNormal">To look for documentation would be appreciated.<o:p></o:p></p>
