That man page is a copy and paste from a white paper.  That feature is a 
TODO and should be removed from the man page.

You might be able to obtain something like that by using a proxy that 
statically maps a given subtree to a given server.  Something like

database relay
suffix "dc=virtual"
overlay rwm
...

rwm rules that rewrite the base DN of a search based on the contents of 
the filter (not a trivial rule, though) to a temporary DN like
(uid=*-b) -> $BASEDN,dc=server1
(uid=*-c) -> $BASEDN,dc=server2
...

Then add

database ldap
suffix "dc=server1"
overlay rwm
rwm-rewriteEngine on
rwm-rewiteContext searchDN
rwm-rewriteRule "^(.+),dc=server1$" "$1" "@:"
rwm-rewiteContext default

database ldap
suffix "dc=server2"
overlay rwm
rwm-rewriteEngine on
rwm-rewiteContext searchDN
rwm-rewriteRule "^(.+),dc=server2$" "$1" "@:"
rwm-rewiteContext default

...

and so on.  The whole thing may need quite a bit of shakedown, and is 
going to be far from efficient, though.
