Package: adduser
Version: 3.121
Severity: normal
Hi,
the useradd documentation says that a user name has a 32 character
limit. We should enforce this as well.
In useradd, this seems to apply to the UTF-8 representation of the user
name, that is, aaääääääääääääääää (two unaccented and 16 accented
characters) is too long while aaäääääääääääääää (two unaccented and 15
accented characters) is not. So putting this restriction inside our
regular expressions is not going to help. Maybe it's just ok to let
useradd enforce this? Currently this seems to work ok, but it looks like
a train wreck:
root@salida-unstable-buildd-amd64-ydvv:/srv# adduser --system
abcdefghijabcdefghijabcdefghijabc
Adding system user `abcdefghijabcdefghijabcdefghijabc' (UID 101) ...
Adding new user `abcdefghijabcdefghijabcdefghijabc' (UID 101) with group
`nogroup' ...
useradd: invalid user name 'abcdefghijabcdefghijabcdefghijabc': use --badname
to ignore
adduser: `/usr/sbin/useradd -r -K SYS_UID_MIN=100 -K SYS_UID_MAX=999 -d
/home/abcdefghijabcdefghijabcdefghijabc -g nogroup -s /usr/sbin/nologin -u 101
abcdefghijabcdefghijabcdefghijabc' returned error code 3. Exiting.
