My first interpretation, add a DEFAULT to the users file with 
"Auth-Type := Crypt" was apparantly wrong:

...
Module: Loaded files 
 files: usersfile = "/usr/local/etc/raddb/users"
 files: acctusersfile = "/usr/local/etc/raddb/acct_users"
 files: preproxy_usersfile = "/usr/local/etc/raddb/preproxy_users"
 files: compat = "no"
/usr/local/etc/raddb/users[148]: Parse error (check) for entry DEFAULT: Unknown value Crypt for attribute Auth-Type
Errors reading /usr/local/etc/raddb/users
radiusd.conf[1068]: files: Module instantiation failed. 
radiusd.conf[1828] Unknown module "files".
radiusd.conf[1763] Failed to parse authorize section. 

So, instead, I changed radiusd.conf's myshadow definition to 
"authtype = Crypt", but authentication still isn't happening.

...

I appologize for being so dense.  In which config file / section should
I try adding the Auth-Type := Crypt statement?
