selinux and /etc/passwd

[Sergiu Giurgiu]

hi,
I've just installed FC3 tonight (clean install) and ... I've came across 
a small problem.
Users cannot be created. I hev created a user at the first-boot wizard, 
I have tried to use the graphical tool, and ... at the console I tried 
to use useradd. The wizard didn't say anything (like everything was ok), 
the user/group manager graphical tool remain blocked when I pressed OK 
to add a new user, but useradd said that it cannot alter /etc/passwd  (I 
don't recall the exact message). As a result, I couldn't add a new user.
To start eventually working, I have disabled selinux and rebooted. 
everthing works fine now.
Given that I'm not quite knowledgeable about selinux (why is it there 
and what is it doing), and this machine functions as a 
workstation/desktop machine, I can say that I'm ok with this solution. 
However I would like to know what was happening. Is it a bug (didn't 
found reports about this)? It's a feature? Can it be fixed? If so, how?
The filesystem installed is reiserfs (does it matter?).
Thank you.

Sergiu.
