SuSE 8.0 : useradd also doesn't like "dots" all of a sudden... eg. useradd -d /var/lib -s /dev/null user4.domain.de no longer works. anyone know howto or why etc. ? thx andre

Why can't I use dots in my User-Name ?
for historical reasons (that means: to stay compatible to non-Suse systems :-) ), user and group names are required to consist of a lowercase letter followed by zero or more lowercase letters or numbers. Dashes in the username are accepted as well.
Is that a security problem or only a YAST2 Problem.
First one. Some implementations of chown expect user and group separated by a dot. If your username was "lars.vaessen", how could an admin of such a system chown you a file? It would go to the different user "lars" and the group "vaessen".

If previous versions of yast didn't mind dots, they are broken. -- Johannes Franken Professional unix/network development mailto:jfranken@jfranken.de http://www.jfranken.de/
