The returned value should be checked on other references as well.
are you planning to update this patch? I think it would be a good idea.
Additionally I would like to ask you if you can fix the
HAVE_KRB5_PRINCIPAL_GET_REALM branch of sss_krb5_princ_realm(). Since
krb5_principal_get_realm() may return NULL I think it is not a good idea
to call strlen() unconditionally.
