The ssh-askpass is a generic executable name for many packages, with similar names, that provide a interactive X service to grab password for packages requiring administrative privileges to be run. It prompts the user with a window box where the necessary password can be inserted. Here, we choose Damien Miller's package distributed in the OpenSSH tarball.
This package is known to build and work properly using an LFS 12.2 platform.

Install ssh-askpass by running the following commands:
cd contrib && make gnome-ssh-askpass3
Now, as the root user:
install -v -d -m755 /usr/libexec/openssh/contrib && install -v -m755 gnome-ssh-askpass3 /usr/libexec/openssh/contrib && ln -sv -f contrib/gnome-ssh-askpass3 /usr/libexec/openssh/ssh-askpass
The use of /usr/libexec/openssh/contrib and a symlink is justified by the eventual necessity of a different program for that service.
As the root user, configure
Sudo-1.9.15p5 to use ssh-askpass:
cat >> /etc/sudo.conf << "EOF" &&
# Path to askpass helper program
Path askpass /usr/libexec/openssh/ssh-askpass
EOF
chmod -v 0644 /etc/sudo.conf
If a given graphical <application> requires administrative privileges, use sudo -A <application> from an x-terminal, from a Window Manager menu and/or replace "Exec=<application> ..." by "Exec=sudo -A <application> ..." in the <application>.desktop file.
