[tac_plus] Default user config values

[David Clymer]

I want to authenticate users via PAM & LDAP, but since tac_plus doesn't
allow me to specify PAM as a default authentication method, I modified
config.c to allow users which don't have specific configs, to use a the
authentication method (an any other config values) from the DEFAULT
user. I'm not completely sure this isn't stupid for one reason or
another, but I need that functionality. In any case, here is the simple
change I made:

+++ tacacs+-F4.0.4.18-davidc/config.c	2009-05-20 12:35:34.000000000 -0400

     }
 
     /* found the entry. Lookup value from attr=value */




Enjoy, and thanks for writing tac_plus!
