Bug Description

When upgrading nslcd to 0.8.4ubuntu.0.1 the "base" entry in /etc/nslcd.conf was overritten. From reading nslcd.postinst the script rebuilds nslcd.conf from debconf. The values in debconf are incorrect. It is unclear where the values in debconf came from. When nslcd restarted it failed due to a missing base entry and the system became unuseable.

nslcd.postinst should not replace a working /etc/nslcd.conf with a broken on.

The debconf entries apear to come from nslcd.config. In read_config() entries from nslcd.conf are put in debconf. However the sed regex does not take into consideration the "base [map] dn" syntax as noted in nslcd.postinst.

workaround:

put the "base" entry after any "base <map>" entries.

This has been fixed in development and an upcoming 0.8.10-2 release is expected to fix this.

Note that with 0.8.5 or newer the workaround would be to place the empty "base" before the other "base <map>" entries.

  * ensure that time is set before starting k5start to ensure that Kerberos
    ticket is granted (closes: #659227)
  * properly parse and write configuration options with an optional map
    parameter during debconf configuration (LP: #1029062)
