I encountered the same error on karmic. Following this user guide: http://ubuntuforums.org/showthread.php?t=1313472
The error appears after step 1: apt-get -y install slapd ldap-utils The /etc/ldap/scheme directory is empty. To resolve, I copied the .ldif files from another machine. However, I have other errors at present which prevent me from completing the installation. -- package slapd 2.4.18-0ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 https://bugs.launchpad.net/bugs/477257 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openldap in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
