Hm. sounds like sa-learn uses the $HOME environment variable instead
of doing a getpwuid() call. Bad sa-learn. Here's something a little
more robust in Perl that you can run as root:

perl -e 'for $user (@ARGV) { $>=getpwnam($user) or next; $ENV{HOME} = (getpwuid($>))[7]; system(q#/usr/local/bin/sa-learn --force-expire#); $>=$< }' joe bob sally

That's all one line, btw--be sure to unwrap it if your mailer mangles
it. Here's what it does. For each user listed on the command line:

  - drop privileges to that user
  - set the HOME environment variable for that user
  - run sa-learn (under that user's UID)
  - become root again and try the next user

You could stick it in a file if this is something you want to run from
time to time (e.g. from a cron):

<snip>
#!/usr/local/bin/perl
## root should run this as "sa-learn-all user1 user2 user3"
for $user (@ARGV) {
    $> = getpwnam($user) or next;
    $ENV{HOME} = (getpwuid($>))[7];
    system(q#/usr/local/bin/sa-learn --force-expire#);
    $>=$<;
}
</snip>

Save it to a file and call it something like "sa-learn-all". Be sure
to make it executable (chmod 755 /path/to/sa-learn-all).  Then run it
like this from cron:

  23 5 * * * /path/to/sa-learn-all joe bob sally
