This is the problem with the long delay during the post-install.

Three others?  Which ones?

Do you have the updates for NIS (IIRC pam/nfs-utils/ypbind)?
Try running authconfig again, and select md5/shadow.  Convert the passwd
file and see if that works.  When setting up NIS, I make an entry in
/etc/hosts for the name/IP of the NIS server in the post-install.  I also
use shadow.
