destroy credentials if krb5_kuserok() call fails. Stops credentials being
delegated to users who are not authorised for GSSAPIAuthentication when
GSSAPIDeletegateCredentials=yes and another authentication mechanism succeeds;

This issue does not affect RHEL3 and RHEL2.1 as they do not contain GSSAPI
