- Updated the address for the FSF in the opening comment. - Standardized the format of the opening comment, including adding a brief description of what's in the file for those that lacked it. - Added some missing copyright lines. - Some minor whitespace tweaks (in a few of the files).
- Use the MD4_SUM_LENGTH define in place of some hard-wired values. - Pass the hostname in to auth_server(). - Generate a unique error for each failure type in auth_server() so that the log-file contains why the authorization failed. - Don't use sscanf() to parse the client's auth-challenge response.
