You would need to have a TGT. In a Kerberos environment, you should normally 
have things in place to ensure this (e.g. pam_krb5 for auth and session would 
accomplish getting an initial TGT on a login session).

There are other SASL mechs that may be of use, but also require other 
infrastructure or credential distribution. Kerberos/GSSAPI has other 
advantages as well, due to wide support/adoption.
