FC 3, permissive, strict: Error! Unable to set executable context.

[Browder, Tom]

I just turned on SELinux on my FC 3 box at home (permissive, strict).
No problems and I'm building large /var/log/message file as we speak.

However, I did the same thing on a box at work and when I try to login
as a normal user I get an error messge on the gdm login screen that
says:
  
  Error! Unable to set executable context.

And it won't let me login.  But I can still login as root OK.

What am I doing wrong?

Thanks.
