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? Henk van Lingen, Systems Administrator & DBA </blockquote><div> 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"; }; </div> </div>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.
