Null passwords

[David Maier <dave@xxxxxxxxxxxxxx>]

I'm running an FC2 system on which I don't care about password 
security.  PAM is running. I've been all over the HOWTO's and manual and 
cannot find how to enable null passwords for a user. I've tried putting 
a nullok argument into stacks in the login, passwd, and system-auth PAM 
services, to no avail, and have run out of ideas. Obviously I'm a newbie 
trying to get a handle on where to even look.

Thanks for your help.
