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) ...
