I don't think the configuration upgrade code is the issue here (that would probably only cause issues with some downgrades). Furthermore, from a quick glance it seems the patch disables debconf configuration altogether.
The Debian packages contains numerous fixes to the debconf handling and configuration parsing that most likely fix the above issues: * don't clear the tls_reqcert option when using ssl without the start_tls option or an ldaps:// URL fixed in 0.8.8-3 (Debian bug https://bugs.debian.org/672301) patch: http://arthurdejong.org/viewvc/nss-pam-ldapd?revision=1687&view=revision * fix a problem in sed logic for commenting out disabled options fixed in 0.8.10-3 (Debian bug https://bugs.debian.org/689296) patch: http://arthurdejong.org/viewvc/nss-pam-ldapd?revision=1777&view=revision * make whitespace matching consistent in regular expressions fixed in 0.8.5 patch: http://arthurdejong.org/viewvc/nss-pam-ldapd?revision=1543&view=revision * get the first configuration value instead of the last because that one is also written fixed in 0.8.5 patch: http://arthurdejong.org/viewvc/nss-pam-ldapd?revision=1567&view=revision * properly parse and write configuration options with an optional map parameter during debconf configuration fixed in 0.8.10-2 (Launchpad bug https://bugs.launchpad.net/bugs/1029062) patch: http://arthurdejong.org/viewvc/nss-pam-ldapd?revision=1740&view=revision * properly handle preseeding and reading values from the configuration file by forcefully overwriting debconf values from nslcd.conf and not overwriting debconf values when reading other configuration files fixed in 0.8.13-2 (Debian bug https://bugs.debian.org/717063) patch: http://arthurdejong.org/viewvc/nss-pam-ldapd?revision=2016&view=revision ** Bug watch added: Debian Bug tracker #672301 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=672301 ** Bug watch added: Debian Bug tracker #689296 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=689296 ** Bug watch added: Debian Bug tracker #717063 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=717063 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1350778 Title: Upgrading nslcd on precise rewrites /etc/nslcd.conf, leaving users with unusable systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nss-pam-ldapd/+bug/1350778/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
