That's right.

As far as I can tell, the LDAP servers at yahoo and bigfoot don't support
anything of the kind. Their implementation seems to support the bare
essentials, but nothing more. For example, it looks like you can't do two
searches on the same connection, either!

I haven't found any way of doing something like it on the Novell DS either.

That should work on LDAP V3-compliant servers. Netscape DS supports it,
presumably Innosoft's server as well. For OpenLDAP, you can try this:

base: cn=config
scope: base
filter: objectclass=*

You get an attribute 'database', with one value:

ldbm : o=suffix1 : o=suffix2  [ and so on ]

This works for UofM 3.3 as well.
