I've just pushed up a FDW for the unix/linux user database. (Think /etc/passwd and /etc/group, although on many systems it could be configured to pull data from LDAP or another network source.)
It works but I'm not sure how to write the tests since I seem to require a user mapping even though I commented out a few places where the option checking referred to them.
Is there documentation for that somewhere? I've looked at several FDW problems but don't recall seeing this anywhere.
Thanks,
Bear
