Subject: [PATCH] Don't crash on bogus keys in login.defs if PAM is enabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Without this patch, PAM enabled builds crash when encountering an
invalid key in login.defs or key overrides because of array overflows

To reproduce, simply
	useradd -K Windows=broken
