Hi James. Thanks for bringing that up. In reviewing the /etc/nsswitch.conf files they LOOKED identical. I then went into one of the errant ones and saw that passwd looked odd in the editor. I retyped that line and the and shadow and group lines and restarted and indeed it worked. Not sure how that occurred but it did work. Thanks Much!
