Our discussions reached the same conclusion: the ability to propagate
to multiple servers made it worth it to go ahead with ldap.  Good to
know that there is not a limit to the tdb format, though, that causes
it to behave terribly when the number of entries gets large.

I would suggest the documentation be clarified on this point, and in
fact would be happy to update it myself, but have not yet gotten
around to determining how one contributes.
