Some LDAP servers (iPlanet/Sun, for one) support a "virtual list view" or
sometimes called a "browsing index".  This lets you specify a search
filter and specify a certain range of entries from the result set.  So you
might have a search filter of (cn=b*) and specify that you want entries
1-100.  Then you do the same search and specify entries 101-200, etc.

This is basically the only sane way to browse a very large number of LDAP
entries, if you can't do a narrower search.

If this sounds useful, I'd be willing to investigate if it is possible to
use virtual list views from php.
