Adduser devel - Sep 2006 - Bug#389160: adduser: Please allow "@" in user names

Package: adduser
Version: 3.97
Severity: important

Please allow creation of user names containing an "@" character.
Currently, this does not work, even if NAME_REGEX has been changed
accordingly.

Background: I want to use PAM/saslauthd as configuration backend for a
virtual-domain-enabled Cyrus IMAPd.  For this to work correctly, my user
names must look like email addresses.

Regards,

uLI

Severity important as per suggestion of the maintainer.

Tentative fix has been checked in to svn.  It Works For Me (TM), but
another look wouldn''t hurt before release.

Till now a failing check using the internal regexp prints an error message
and exits adduser. If we remove that exit (like you did), we should clearly
state the the message is a warning and no error.

This would require another (but easy) update of the po-files :-|

I''ll check-in that.

Your fix reduces an error to a warning, allowing _all_ sorts of bad
characters in user names. I am not sure whether I like that. Actually,
I hate the idea.

I think that we should

(a) investigate whether @ in a user name can cause serious harm, and
    if not,
(b) add @ to the list of allowed characters.

Greetings
Marc
