[Cooker] adduser problems

[greg]

Hi all,

I need to be able to addusers that have a username that is a number.

I get the following message whenever I atempt this.

[root@mail /]#  adduser 0413565738
adduser: invalid user name `0413565738'
[root@mail /]#

I have only tried this on 7.0 and cooker.

HELP!
