Inegrated and Forms Based Authentication OWA 2010

Hi,

Does anyone have OWA setup with integrated authentication for clients internally and forms based authentication for clients external?

I'm sure it's possible but have no idea how to go about it.

Thanks

Do you have an ISA server, if so you could probably set up two listeners, one fir internal and one for external. As ISA takes over the authentication role it would just be a case of telling ISA to use the required types of authentication for each listener.

If not this is a lot more tricky, I only ever did it with 2003 but you can make a copy of the exchange web services bit in IIS and with some reg hacks I think that it is possible to use two authentication types like this.

You should implement Microsoft TMG. For integrated authentication point your users to the internal URL of the Exchange box.

In TMG, point the Lister to the same URL as the internal URL on the exchange box.

You can also be a little clever with DNS and host file entries and keep the same URL internally and externally.

did you manage to configure this? I'm after the same with exchange 2007!
