Description of problem:
I just installed a fresh copy of Fedora Core 2 from the development
directory.  After the first reboot, I tried to add a user as follows:

useradd sen

Then received the following error message:

useradd: cannot rewrite shadow password file

If I manually add the user to /etc/passwd, when I try to assign a
password to the user, the passwd command hangs.

After the _second_ boot, I saw the X windows screen from the firstboot
program telling me to set up a non-root account.  When I tried to add
the user 'dbc' this time, I received an error.  Here is the contents
of the firstboot error log:

Traceback (most recent call last):
  File "/usr/share/firstboot/firstbootWindow.py", line 269, in
nextClicked 
    result = module.apply(self.notebook)
  File "/usr/share/firstboot/modules/create_user.py", line 225, in apply 
    self.admin.modifyGroup(groupEnt)
RuntimeError: data not found in file


Version-Release number of selected component (if applicable):
pam-0.77-33, kernel-2.6.2-1.87

How reproducible:
Always

Steps to Reproduce:
1. Install fresh Fedora Core 2 test1
2. Try 'useradd' command
3.
