I was mistaken earlier. LDAPv3 connect is possible. It just has to use
simple authentication, not SASL.

I removed these. I then moved the OpenLDAP libs from /usr/lib to
/usr/lib-backup, and removed all the extraneous copies lying around.

Finally, I reinstalled OpenLDAP 2.3.39 from source into /usr/lib and then
rebuilt python-ldap into the python2.4 site-packages.

ldd _ldap.so gives this:

linux-gate.so.1 =>  (0xffffe000)

libz.so.1 => /usr/lib/libz.so.1 (0xb7c17000)
/lib/ld-linux.so.2 (0x80000000)

But the old error has returned:

What should they be set to? I used this in the last compile:

library_dirs = /usr/openldap-2.3/lib /usr/lib
include_dirs = /usr/openldap-2.3/include /usr/include/sasl

Before, I was leaving them unchanged.

I'm going to set up a fresh Ubuntu system. If it works, I'll rebuild the
current server from scratch.

Thank you very much for all the help, Michael. This is a frustrating
problem.
