I suspect that you used the Solaris LDAP libraries when you compiled
Sudo.  I believe if you compile it against the OpenLDAP libraries it
will allow you to specify multiple LDAP servers in the configuration
file.  (The failover code is in the LDAP libraries)

I hope this helps.  Please let me know if you need more details and I
will be glad to provide them.
