Nsswitch and Pam.d problem

[B1smooth]

I changed my authentication scheme via authentication gui to include 
LDAP and maybe SMB(can't remember). I rebooted Ydl and I was unable to 
login as root or any users. I downloaded ext2 support for osx, mounted 
my root partition and edited my nsswitch.conf file.  I removed all 
instances of ldap and nis from the
file to look like

passwd: files
group:   files
shadow: files

I even changed the public_key to files.
  I still can't get into my YDL 3.0.1 distro. Do I need to edit something 
in my pam.d folder? Anyone have any other suggestions...I have full 
access to my root partition in 10.3.
