<div>Hi, </div>
<div><br>
</div>
<div>I followed the instructions on the SHIB2 wiki to enable the kerberos login handler 1.3. After struggling with it for a few days, I have reached a point where I can see the login page but when I try to login, I do not see any requests to test the user against
the principal using the key tab file. Instead, I see a simple HTTP 401 but I am not user if its a problem with the header (so I can check my apache configuration) or calling the servlet. The error is shown below (TRACE level on for the kerberos handler. Any
tips or hints to put me in the right direction would be appreciated.</div>
