I did not misunderstood the word, this is _EXACTLY_ how I understood it! I
fucked up, OK?
I'm the author of the xAdmin package, therefor I messed up the chown'ing of the
file... I
didn't think about the problem I described above.
I have now fixed this. I should not close the bug (according to James), until I
have fixed
it permanently, which will happen any day (I hope :).

Sorry, I meant:
chown("/etc/shadow", "root", "shadow");
Where I find 'shadow' by doing a:
getgrnam('shadow')
Maybe I should do a
getpwuid('0')
to find the name of the root user? :)
BTW. Is there a secure way of locking files, that work on any program? Say
admin 1 is using
xAdmin to change/add etc a user, and admin 2 is using emacs (or, yuck, vi :) to
do the same...
Admin 1 is starting his prog first, how would admin 2 (with editor of his/her
choice) know
about this...
