Depends on what that feature actually looks like. Feel free to submit a
proposal
on the ‑devel mailing list, including background info on what HAproxy
protocol
looks like, and what exact behaviors you want it to provide.
I wonder: Would it be possible to use a specific named bind for on-campus
hosts, and use the name used for binding to controll further access?

Hmm, I'm not completely sure what you mean here? Do you mean an
authenticated bind? Our current IP address access control allows
anonymous users on campus access to attributes that anonymous users
off-campus cannot get to, and it also limits authenticated binds for
non-service accounts to on campus only.

Yes, authenticated ("named" vs. anonymous) binds.
anonymous users on campus access to attributes that anonymous users
off-campus cannot get to, and it also limits authenticated binds for
non-service accounts to on campus only.
I'm aware that this might require a change like having to use an authenticated bind
for "get more" from LDAP (as opposed to anonymous binds).
