I gather other folks have been saying to fix Domain =, and make sure
Method = nsswitch is not commented out, in /etc/idmapd.conf. Other things:
   1. *also* in /etc/idmapd.conf, go further down, and comment out or
           delete the *other* schema - for example, the UMICH schema is
           by default enabled, for some reason. *Definitely* disable that.
           Scroll to the bottom of the file, to make sure nothing else is
           on by default.
   2. nsswitch - check /etc/nsswitch.conf

Then restart idmapd.
