Yes. The simplest answer is to use the SUNWfiles backend (see
dhcp_modules(5)), and share the files via NFS between servers. The more
complex (but much more scalable) way is via NIS+ (on Solaris 10, but not
OpenIndiana; NIS+ is dead). Amusingly, the man page still talks about
"three" built-in mechanisms but then describes only two.
Good to see you're still better at noticing details than most anyone I
know :-)
You can also write your own backend to do anything you want; see the
"Solaris DHCP Service Developer's Guide:"

That would be my suggestion, too.
Perhaps a shared LDAP backend can be implemented?
I'm sure that could be done as well. I don't recall if it was ever
done, but I would have expected that it would have been an ARC-required
portion of the NIS+ to LDAP transition strategy. I'd expect that Dave
Miner at Oracle would know for sure if anyone does.
No, we never got around to building one; I seem to recall we'd started a
prototype back in the late '90's but it never got to be a priority.
