+ [Original Report]I was trying to "apt-get install dpkg" to work around
+ #944452 and got the following while trying to upgrade slapd:

  Setting up slapd (2.4.28-1.1ubuntu4) ...
  Use of uninitialized value $type in ucfirst at /usr/share/perl5/Debconf/AutoSelect.pm line 35.
    Backing up /etc/ldap/slapd.conf in /var/backups/slapd-2.4.21-0ubuntu5.7... done.
    Moving old database directories to /var/backups:
    Loading from /var/backups/slapd-2.4.21-0ubuntu5.7:
    - directory dc=interlinx,dc=bc,dc=ca... failed.

  Loading the database from the LDIF dump failed with the following
  error while running slapadd:
      4f9c4903 slap_sasl_init: auxprop add plugin failed
      slapadd: slap_init failed!
  dpkg: error processing slapd (--configure):
   subprocess installed post-installation script returned error exit status 1

  This looks to be related to http://bugs.debian.org/cgi-
  bin/bugreport.cgi?bug=665473 where message #10 (http://bugs.debian.org
  /cgi-bin/bugreport.cgi?bug=665473#10) in that bug says:

  This looks like a repeat of bug #628237.  However, slapd 2.4.28-1.1/amd64
  has a dependency on libsasl2-2 (>= 2.1.24), ...

  Looking at the package info for slapd:

  Package: slapd
  Priority: optional
  Section: net
  Installed-Size: 4064
  Maintainer: Ubuntu Developers <ubuntu-devel-discuss at lists.ubuntu.com>
  Original-Maintainer: Debian OpenLDAP Maintainers <pkg-openldap-devel at lists.alioth.debian.org>
  Architecture: i386
  Source: openldap
  Version: 2.4.28-1.1ubuntu4
  Replaces: ldap-utils (<< 2.2.23-3), libldap2
  Provides: ldap-server, libslapi-2.4-2
  Depends: libc6 (>= 2.15), libdb5.1, libldap-2.4-2 (= 2.4.28-1.1ubuntu4), libltdl7 (>= 2.4.2), libodbc1 (>= 2.2.11) | unixodbc (>= 2.2.11), libperl5.14 (>= 5.14.2), libsasl2-2, libslp1, libwrap0 (>= 7.6-4~), coreutils (>= 4.5.1-1), psmisc, perl (>> 5.8.0) | libmime-base64-perl, adduser, lsb-base (>= 3.2-13)

  We can see that it's not requiring a newer libsasl2-2.

  At this point I did an "apt-get install libsasl2-2" and it installed the
  new libsasl2-2 and allowed the configuration of slapd to finish.

  -- SRU Justification --

  [Impact]
  slapd's maintainer scripts make use of utilities like slapcat and slapadd which require a running slapd server, however, the relationship between slapd and libsasl2-2 packages do not take into account a binary incompatability introduced with 2.4.28-1.1.  As a result, libsasl2-2 is not upgraded until after slapd, slapd fails to start (with error msg cited in the bugs), and maintainer scripts fail during upgrades with a debconf error like: http://paste.ubuntu.com/965636/

  [Development Fix]
  The issue has been sorted in Debian and in Quantal with the recent merges.  A thorough explanation of the fix is available at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=628237#163 .  The solution is to update cyrus-sasl2 with:
    - Breaks: 'slapd < 2.4.25-4' on libsasl2-2
    - shlib dependency on 2.1.24 for libsasl2-2
  Both of which have been applied to packaging in Debian and synced into Ubuntu Quantal.  A no-change rebuild of openldap against the new sasl dependency is required as well.

  [Stable Fix]
  The two one-liners from above should be back-ported from 2.1.25.dfsg1-4 packaging and applied
  to cyrus-sasl2 packaging in Precise.  A no-change rebuild of openldap against the newly updated dependency is required as well.

  [Test Case]
  To reproduce, install slapd on a lucid installation, populate a minimal LDAP directory and do-release-upgrade.  A script to populate a minimal database can be found  at http://paste.ubuntu.com/965633/.

  [Regression Potential]
  Minimal. Packaging changes ensure proper ordering of upgrades during dist-upgrade and do not touch original source tree.
