Hello Managers,
This list is terrific as usual! Fast answers to
my problem came from:
Randy M. Hayman <haymanr_at_icefog.sois.alaska.edu>
Marco Campani <campa_at_ge.INFM.it>
Both said that I should change this line in my program:
set_auth_parameters();
to this:
set_auth_parameters(argc, argv);
This solved my problem. Thanks, Randy and Marco!
Now when I compile it on DU 4.0B it runs fine.
Also, very helpful were:
Pam Woods, Systems Manager <axsymgr_at_UAA.ALASKA.EDU>
John P. Speno <speno_at_swarthmore.edu>
Jo Knox <fxjwk_at_aurora.alaska.edu
Thank you all for responding. My original post is below.

------- Original Post ---------------------------------
Hello Managers,
I run DU 4.0B on one AlphaServer 2100 and DU 3.2d-1 on another.
Both run C2 Security. I have a handy little C program that I
use to set the expiration date on a user's account. (Somebody
on this listserver gave me a copy of it quite a while ago.)
On the 4.0B machine, I can compile it just fine, but when I run
the program I get a core dump:
# ./expireone someuser
Memory fault - core dumped
The only way I can get this program to run successfully on the
4.0B machine is to do the actual compiling on the 3.2d-1 machine,
and then copy the resulting binary over to the 4.0B machine:
# ./expireone someuser
someuser will expire on Mon Jun 30 01:00:00 1997
I've installed the second major patch for 4.0B that Digital
has made available, but not the third. I'll be installing that
third patch within a week or two just to stay current, but I
don't have any reason to suspect that this will fix my problem.
Has anyone got any ideas on what may be wrong? I'll summarize
any help I get. I've included a copy of my small c program
below. Please note that the original program was interactive
and that I changed it. It is crude (the date of expiration is
now hard-coded!) but does what I need.
Thanks for any help you can give me!

/*
Usage: expireone USERNAME
This program expires one user at a time. It is no longer
interactive, so you can use it in a shell script, within a
loop construct to expire a list of users.
Just hard code the date for expiration in the code below,
recompile, and you are ready to use this program.
To compile: cc expireone.c -o expireone -lsecurity
