After googling around some time, I now have a working ldap/pam
configuration. I installed libpam-ldap libnss-ldap ldap-utils
and edited a hand full of configfiles.
Now I want to do this all unattended at install time. I want to install
the packages, and afterwards copy the configfiles in place.
So I have:
DEBIAN_FRONTEND='noninteractive' apt-get -y install libpam-ldap
libnss-ldap ldap-utils
in a script which is called by
d-i preseed/late_command string chroot /target ....
This however does not seems to work, it keep hanging in the apt-get/conf
process.
Looking for an alternative I found debconf, but that does:
fana:/root-# debconf -f noninteractive apt-get install libpam-ldap
libnss-ldap ldap-utils
debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by
another process: Resource temporarily unavailable
dpkg: error processing libnss-ldap (--configure):
o
subprocess post-installation script returned error exit status 20
dpkg: error processing libpam-ldap (--configure):
subprocess post-installation script returned error exit status 20
Errors were encountered while processing:
libnss-ldap
libpam-ldap
E: Sub-process /usr/bin/dpkg returned an error code (1)
fana:/root-#
Ideas to get those debconf questions silenced?

Hey Henk,
Try setting the priority to the questions to be asked:
$> cat /etc/apt/apt.conf.d/70debconf
// Pre-configure all packages with debconf before they are installed.
// If you don't like it, comment it out.
$> man dpkg-preconfigure
...
// Pre-configure all packages before
// they are installed.
DPkg::Pre-Install-Pkgs {
"dpkg-preconfigure --apt --priority=high";
};
Perhaps you can do this from the command line when you call "apt-get". All
you needed to know was the option name "DPkg::Pre-Install-Pkgs".
$> man apt-get
Though you seem to be very well informed.
Hope that helps
