The ClearTrust auth servers have to be told where to go looking for the
name, so to expound on the CT side of things:

User tries to access a URL that is protected by the CT agent (installed on
webserver). CT agent redirects the user to the logon form. User enters
name/pw in form.
CT agent passes name/pw to the CT auth server. Auth server looks at it's
config and tries the LDAP bind to the configured directory. On successful
bind and permissions, user is given a cookie and redirected back to
original URL.

So, the problem is that CT can only go looking in one place for the user
(actually two, but that's another story and not really helpful anyway). 
It can, apparently, handle LDAP referrals, so if one LDAP directory can
refer to others that are "parallel", this might be pretty simple ; )

Does that make sense?

Thanks,
