Problem accessing subversion repo with SASL/LDAP authentification

I've configured subversion server to work with LDAP. All works fine. But I can't access to subversion repos from Redmine.

Info:

Redmine 1.4.7.stable (Bitnami stack)
MySQL 5.5.28
Ruby 1.9.3p327
Rails 2.3.15
Subversion server version 1.7.8, Cyrus SASL authentication is available.
Subversion client version 1.7.5 - build-in bitnami stack

configuration.yml

scm_subversion_command: /usr/bin/svn
scm_mercurial_command:
scm_git_command:
scm_cvs_command:
scm_bazaar_command:
scm_darcs_command:

And when I try co access repo from command line redmine server or from redmine project I've got error:

production.log

<list
    path="svn://mysvnserver/myrepo">
Rendering template within layouts/base
Rendering common/error (404)
Completed in 134ms (View: 35, DB: 3) | 404 Not Found [https://redmineserver/redmine/projects/myproject/repository]

error.log (Apache)

svn: E210007: Unable to connect to a repository at URL 'svn://mysvnserver/myrepo'
svn: E210007: Cannot negotiate authentication mechanism

/var/log/messages

unable to dopen /usr/lib/sasl2/liblogin.so :wrong ELF class: ELFCLASS32
unable to dopen /usr/lib/sasl2/libsasldb.so :wrong ELF class: ELFCLASS32
unable to dopen /usr/lib/sasl2/libplain.so :wrong ELF class: ELFCLASS32
No worthy mechs found

So both svn CLI and redmine can't connect to Subversion server with SASL/LDAP because they use 32bit SASL library.

SOLUTION

As I found Bitnami Redmine stack has own SASL library located in /opt/redmine/common/lib and this library tries to load 32bit SASL auth libraries. I removed files /opt/redmine/common/lib/libsasl* and all works fine.

P.S. WMD-editor makes me cry :'(
