Our organization has users spread out across multiple AD domains. Is it possible to specify more than one ldap server for Umbraco to authenticate against for the backend?

For example, I'm in domain1.ourdomain.org, so if I make my LDAP://domain1.ourdomain.org, then I can authenticate. But I also have users in domain2.ourdomain.org that I need to authenticate.

The <providers> section of umbracosettings.config only seems to accept one provider, unless I'm missing something.

Does anyone have experience with a problem like this?

Regards,

Ben
