Every howto or reference I can find tell me that I need to execute $ sudo apt-get install libpam-ldap libnss-ldap but this reports: Reading package lists... Done Building dependency tree... Done E: Couldn't find package libpam-ldap My /etc/apt/sources.list contains the following: deb <a href="http://za.archive.ubuntu.com/ubuntu" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://za.archive.ubuntu.com/ubuntu</a> breezy main restricted deb-src <a href="http://za.archive.ubuntu.com/ubuntu" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://za.archive.ubuntu.com/ubuntu</a> breezy main restricted deb <a href="http://users.lichtsnel.nl/%7Eseveas" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://users.lichtsnel.nl/~seveas</a> breezy-seveas freenx deb <a href="http://mirror.ubuntulinux.nl/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://mirror.ubuntulinux.nl/</a> breezy-seveas freenx deb <a href="http://mirror2.ubuntulinux.nl/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://mirror2.ubuntulinux.nl/</a> breezy-seveas freenx deb <a href="http://mirror3.ubuntulinux.nl/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://mirror3.ubuntulinux.nl/</a> breezy-seveas freenx deb <a href="http://free.linux.hp.com/%7Ebrett/seveas/freenx/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://free.linux.hp.com/~brett/seveas/freenx/</a> ubuntu-seveas freenx deb <a href="http://seveas.ubuntulinux.nl/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://seveas.ubuntulinux.nl/</a> breezy-seveas freenx and I have executed $ sudo apt-get update Is there some other site that I need to add to this file? For that matter, I am pretty new to Ubuntu (and Debian) so if anybody could provide me with a known good sources.list or tell me what I am doing wrong, assuming that that is not the problem, I wou appreciate it. Thanks, Mike
