I mean this:

diff --git a/source3/client/smbspool_krb5_wrapper.c 
b/source3/client/smbspool_krb5_wrapper.c

         env = getenv("AUTH_INFO_REQUIRED");

          /* If not set, then just call smbspool. */
-       if (env == NULL || env[0] == 0) {

                                "execute smbspool");
                 goto smbspool;

or maybe it is not needed because cups will not set env 
AUTH_INFO_REQUIRED if "AuthInfoRequired none" ? I've looked into 
cups/scheduler/job.c, seems that it does set AUTH_INFO_REQUIRED=none 
env, but I'm not sure at all.

Also, I'm not sure that cases like AUTH_INFO_REQUIRED=xxx,none or 
AUTH_INFO_REQUIRED=none,xxx are not possible.
