- *      auth_pass.c  ( $Revision: 6141 $ )
- *
- * Abstract: 
- *
- *     This module is the complete source for a sample "authinfo generic" 
- *     program.  This program takes a user's login name and password
- *     (supplied either as arguments or as responses to prompts) and
- *     validates them against the contents of the password database.  
- *
- *     If the user properly authenticates themselves, a nnrp.auth style
- *     record indicating the user's authenticated login and permitting
- *     reading and posting to all groups is output on stderr (for reading by
- *     nnrpd) and the program exits with a 0 status.  If the user fails to
- *     authenticate, then a record with the attempted login name and no
- *     access is output on stderr and a non-zero exit status is returned.
- *
- * Exit statuses:
- *     0       Successfully authenticated.
- *     1       getpeername() failed, returned a bad address family, or 
- *             gethostbyaddr() failed.
- *     2       Entry not found in password file.
- *     3       No permission to read passwords, or password field is '*'.
- *     4       Bad password match.
- *
- * Environment:
- *     Run by nnrpd with stdin/stdout connected to the reader and stderr
- *     connected back to nnrpd.  This program will need to be run as suid
- *     root on systems where passwords are stored in a file readable only by
- *     root.
