The version mismatch on shared library versions is indeed usually what
the problem is.
You need to run 'ldd' on all Apache modules, all PHP modules if using
PHP, and Python LDAP modules and work out which LDAP client libraries
they use.
Normally Apache mod_auth_ldap would use self contained LDAP client
implementation and so it shouldn't be an issue unless symbols not
being namespaced, but may be possible (not sure) to tell it to use
distinct LDAP client library as well.
See:
http://code.google.com/p/modwsgi/wiki/ApplicationIssues#MySQL_Shared_Library_Conflicts
This is about MySQL, but same sort of issue. See how 'ldd' command is
used in that case to check library versions and do similar thing for
LDAP stuff.
