Yes you can, that's what an ORDERING matching rule is for. But as
Dieter said, it's a bad idea to modify the schema definition of standard
attributes. Also you can't index for caseExactOrderingMatch.

The filter would be fine if uid has an ORDERING rule.
(Well, except filers should have parens around them: "(uid>=branch)".
Not all clients insert missing parens.)
As far as I can tell from the LDAP standard, the extended filter
should work, but it doesn't. (uid is present and is not smaller than
"branch".) I may have said that before, but I don't remember if the
answer is that I'm confused or that I should have filed an ITS.
