Howard debugged this on IRC and it turns out that our (mine and _ranger_'s) libunixodbc has lt_dl* symbols in it. Relinking slapd without the unixodbc lib fixes it.

Yes, so there are two potential issues - the unixodbc shared library seems to be statically linked with an older version of libltdl. I didn't run into this problem on my build because I don't have that odbc library. Anyway, due to the link order of the libraries, the lt_dlopen in this library gets used before the linker resolves to the system's libltdl.so, and it seems that this version of lt_dlopen doesn't automatically export the symbols of modules that it loads.

I'm guessing the reason this is a problem in 2.3.33 and not in 2.3.32 is because there is a new dependency in 2.3.33 between back-meta and back-ldap.

The other part of this is that the slapd binary should not be getting linked against -lodbc when back_sql is built as a module.

Although, if back-sql is built statically, and other backends are dynamic, this problem may still crop up. It seems that fixing -lodbc would be required then.

I've hit this same problem tonight (no sql though):

Thanks.
