Redirect bind requests to another server

[Andreas Moroder <andreas.moroder@sb-brixen.it>]

Hello,

we have a web application that autenticates via openldap. Now a second
hospital should use this same application, but they have their own
autentication server, active directory in this case.

In our network the users authenticate giving their username ( amoroder
in my case ) and password. Is it possible to configure openldap to
redirect the bind request to the remote server when the username
contains an extension like jsmith@remote ? Does this work with AD as
second/remote authentication server ?

Thank you very much
Andreas
