I see. I can, indeed, remove Auth-Type := LDAP from the users file and it still works. Cool! However, the behavior described in the documentation is not what I'm seeing, and I'm still getting (contrary to what I said in my previous email) authorization requests not being proxied, even though I have, in my authorize section, the "suffix" directive previous to "files" and "ldap", which is where I check the LDAP group.... If my realm is @hampshire.edu, everything works as I want it to, because it doesn't proxy. But when I try to authenticate as a fake user in my test proxy realm (I just want to see it try to proxy), it looks in the local LDAP database! Huh? It says it's preparing to proxy <authentication>, as it should... how do I make it either proxy authorization as well, or skip authorization for non-local domains? How should I go about this? I must be misunderstanding something. I don't want it to do anything locally if I've set it to proxy!

Uh. OK. That's exactly what I'm doing, and it's working :)
Then it works. It's fine.
That message is for the majority of people who force LDAP to be used for authentication, and the wonder why EAP doesn't work.
Remember: LDAP is a database. It's not an authentication server.
However, is there a better way to do this that I'm not understanding? Why shouldn't I set Auth-Type := LDAP ?
You probably don't need to set it. If you simply deleted that from the "users" file, your configuration would probably still work.
