As far as I know at the moment, IPFire uses an outdated version of htpasswd. On
my system (OpenSuSE 42.1), however, htpasswd is part of the "apache2-utils" package, which
is already installed in the 2.4-x branch:

This difference can also be found when comparing these two links:

Why: see above.

At the moment, I am facing trouble trying to update the htpasswd package. The LFS
file for this seems to life in
	ipfire-2.x/lfs/perl-Apache-Htpasswd.
But there is no external download URL:

include Config

VER        = 1.9

THISAPP    = Apache-Htpasswd-$(VER)
DL_FILE    = $(THISAPP).tar.gz
DL_FROM    = $(URL_IPFIRE)
DIR_APP    = $(DIR_SRC)/$(THISAPP)
TARGET     = $(DIR_INFO)/$(THISAPP)

The Wiki documentation to this topic is not helping: "DL_FROM the url where the archive
can be downloaded from (notice this is a very unusual case where the archive
is in the root directory of the server)." Uh-huh.

I'll try some more, but I am afraid that it might be weekend or so until I really
get this working. Sorry.

Best regards,
Timmothy Wilson
