I could certainly use some enlightenment on those parameters. Not
coming from an NIS world, I'm not that familiar with RFC2307. I gather
RFC2308 is expired and 2307bis was never adopted but both are still used
I did try setting nss_schema to rfc2307bis but it did not help. I
assumed that meant it would use DNs for the group membership but it did
not return them. If it did, would that still work with determining
posixgroup membership, e.g., CUPS authentication which is where this all
started? Thanks - John
