Yeah, estimation is ugly :)   I updated it with a simple workaround
where you can specify a directory, constant size or command outputting
the size on stdout for the size estimation instead.   In your case you
should be able to use dir:/var/lib/ldap/, or you can do something
fancy with a shell command.

Feel free to fork and hack on that if you want to add something.
If/when it's useful I'll merge it back into mainline.

I don't think it would work well with the current framework but in a plugin like this, having a command you could pass to do the estimation would be cool. For the above example, to estimate the size off the top of my head I would have done "du -sc /var/lib/ldap | tail -n1 | awk {'print $1'}" so having a callable mechanism for that would be pretty neat.
