Re: [Bodington-developers] LDAP Authentication - OpenLDAP versusJNDI

[Alistair Y. <ali...@sm...>]

The load balancing will be handy - never got round to that. Why not do an
LDAP bean or something and stick ones for each server in the context, wit=
h
maybe an LDAPManager or something to decide which beans can be used for
authentication, based on round robin-ing and past performance?
authenticate() can then get a reliable bean from the manager and delegate
authentication to it.

If you'd like me to help out just shout. About time I did some more work
on it. I think it's been in there for a couple of years without
modification.

One thing that definitely needs tidied up is the group matching (staff or
student) - I think it's very uhi-centric at the moment!
