AW: [suse-security] Problems creating usernames with dots

Hi Mario,

From: Mario Viana [mailto:marioj@secrel.com.br] Hello,

Well, maybe it´s a little off-topic , but does anybody know why SuSE 8.0 don´t accept creating a username with dots, e.g. , while I try creating the user suse.br :

# useradd suse.br useradd: invalid user name 'suse.br'

Because . is not a valid character for users. What about "chown user.group file" ? Does the . belong to the username or is it the username-group delimiter?

I have seen all the configuration files in /etc/sysconfig, Suse DB and Google and I haven´t found anything related to this topic. =((

Dotted usernames were a bug until SuSE 8.0. regards, Stefan
