Subject: [PATCH] Improve error messages from kadmin change_password
|
|
|
|
The checks for missing option arguments were dead code, because the
|
|
loop condition requires at least two remaining arguments. Instead
|
|
check for at least one argument with a leading "-", and check for too
|
|
many or too few arguments after the loop. Add an initial message for
|
|
unrecognized options.
|
|
|
|
[ghudson@mit.edu: adjusted logic to improve mesages in more cases]
|
|
|
|
(cherry picked from commit 13ba54002d362ebb09be464b4e7ec75050d1348f)
