Re: [Xen-users] Can't add a user to Xen 3.0.3 VM !

["Omer Khalid" <Omer.Khalid@xxxxxxx>]

You are absolute right Mat! SELinux was enabled and disabling it solved the problem :-)

Many thanks to all of you who responded so promptly to my email.

Best Regards, and have a good day!

Let me guess: You have selinux on your machine? If that's the case, you
need to use the "approved" method of adding users. Again, nothing to do
with Xen.

vipw is a special script/application that essentially does "vi passwd".
Not sure what the purpose of the copying of /etc/skel is supposed to do.
