It means exactly #1; in fact, the admin limit must be intended
as a whole, regardless of how you exploit it.  There is a clean
workaround: if you look at slapd.conf(5) in HEAD, you'll see that
you can set a specific "hard" limit for paged resulst, with the
"size.prtotal" keyword, which determines how big (even unlimited)
the limit should be when the results are paged.  This can be done
for specific client identities, including "anonynous", of course.
