1. If not building with PAM, kcheckpass relies on HAVE_SHADOW to decide whether to support shadow passwords. However, this was only set if also building tdm. Consolidate all PAM/shadow configure checks at the top level so these are always set correctly. 2. Consolidate /etc/passwd and shadow password handling The shadow password handler already completely handles /etc/passwd passwords as well, so having a separate handler for just /etc/passwd is pure code duplication.

README
The KCheckPass authentication software: ----------------------------------------- KCheckPass is KDE's authentication program. It is meant to be used by any software in need of user authentication, most notably screensavers. It enhances security be the following means: - It's only a small program, which is hopefully simple enough to allow it to be SUID root. Setting it to SUID root is necessary on Shadow Password systems. - No other program in need of user authentication, must be SUID root. - It provides a single implementation to check passwords. So one only must take a closer look at KCheckPass to ensure password security. It's much easier for programs using KCheckPass to preserve security. Technique: ---------- KCheckPass is a simple password checker. Just invoke and send it the password on stdin. If the password was accepted, the program exits with 0; if it was rejected, it exits with 1. Any other exit code signals an error. Compilation hints: ------------------ Compile with -DHAVE_VSYSLOG if you have vsyslog(). Compile with -DHAVE_PAM if you have a PAM system, and link with -lpam -ldl (If libdl is present). Compile with -DHAVE_SHADOW if you have a shadow password system. Copyright, Author and License notice: ------------------------------------- Copyright (C) 1998, Caldera, Inc.
