The proof-of-concept in CVS HEAD is now working. I haven't thought too hard
about how it interacts with backglue yet, that could be ugly. Probably the
two should be merged.
I've added a chaining wrapper to back-ldap as well. configure like so:
The chaining code only takes effect if an operation on the backend gets an
LDAP_REFERRAL result. For Binds, the request is forwarded on a new connection
to the target server and if it succeeds, then the local connection is
authenticated. For other operations, the request is forwarded on a privileged
connection, using the Proxy Authorization control.
The idea behind chaining is to support a cluster of trusted servers that
collectively contain a DIT. The current implementation only supports one
referral target, since back-ldap currently only handles one URI per backend
instance. There's a bit of extending still needed to make this really useful.
