title: Configure kerberos without krb5.conf
body: <p>I'm using kerberos authentication to login to ActiveDirectory. I'm doing it with GSSAPI.</p>
  
  <p>Currently, I'm using krb5.conf file, that describes the realms, encryption algs and more, and the authentication works fine.</p>
  
  <p>I would like avoid using this file. Can I programmatically configure kerberos, without using this file?</p>
  
  <p>Thanks.</p>
