[Bug 1160896] Re: svnserve in 1.6.17dfsg-3ubuntu3 not linked against libldap-2.4-2 any more

[Klaus Thorn]

This is not a problem for me (original poster) any more. With some
changes to the config files I could get it running.

If I were the only one to have this problem, I would have tried to close
this bug. But since at least one other user seems to have this problem,
I reset the bug status to "new", I hope this fits the workflow here. If
not: Sorry, I improvised :-)

Thanks for posting the helpful, working config files goes to
http://serverfault.com/users/181004/kaeptn

Finally, in hope to help others who are searching for a solution, the
working config files:

/etc/sasl2/svn.conf (I guess this was the most relevant for my setup):

pwcheck_method: saslauthd
mech_list: plain

/etc/saslauthd.conf (only minor changes to what I had anyway):

ldap_servers: ldap://xxx.xxx.xxx.xxx
ldap_use_sasl:no
ldap_search_base: DC=domain,DC=tdl
ldap_bind_dn: xxxx at domain.tdl
ldap_bind_pw: magic_word:)
ldap_mech: PLAIN
ldap_auth_method: bind
ldap_filter: (sAMAccountName=%U)
log_level: 7

/etc/default/saslauthd (only minor changes to what I had anyway):

START=yes
DESC="SASL Authentication Daemon"
NAME="saslauthd"
MECHANISMS="ldap"
MECH_OPTIONS=""
THREADS=5

Title:
  svnserve in 1.6.17dfsg-3ubuntu3 not linked against libldap-2.4-2 any
  more

Status in “subversion” package in Ubuntu:
  New

Bug description:
  I tried to migrate from 11.04 to 12.04 but svnserve does not validate
  users against sasl's ldap auxprop plugin any more.

  in /var/log/auth.log:
   svnserve: could not find auxprop plugin, was searching for 'ldap'

  ... whenever I open a Tortoise-SVN repo-browser on a client machine
  with a URL pointing to this 12.04 server. (No problem with the 11.04
  server.)

  But by using testsaslauthd on the 12.04 server, I AM able to auth against ldap, so I have no reason to doubt saslauthd.
  Also, The error says "svnserve..." not "sasl...".

  Due to the identical configuration of my 11.04 and 12.04
  installations, the only possible reason I could find is the missing
  linking:

  libldap_r-2.4.so.2 => /usr/lib/libldap_r-2.4.so.2

  ... which is present under 11.04 (1.6.12dfsg-4ubuntu2.1) but not under 12.04 (1.6.17dfsg-3ubuntu3).
  I DO have installed the libldap-2.4-2 on both systems.

  So why is it not linked? If this is not a bug, why is it not
  authenticating?

  Details:
  uname -a @12.04 server:
  Linux zeus 3.2.0-34-generic #53-Ubuntu SMP Thu Nov 15 10:48:16 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

  uname -a @11.04 server:
  Linux rogue 2.6.38-8-server #42-Ubuntu SMP Mon Apr 11 03:49:04 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

  I also DO have installed all those library packages on both systems.
  And subversion-tools.
  I also re-installed subversion.
