I am working with Exchange 2010 currently and am wondering how having a domain/sub-domain logon choice being presented on the logon page can be achieved.
Is there anything configurable that exists already within Exchange to enable such a feature? An admin had something on the logon.aspx page but it appears to get wiped out/overwritten by Exchange 2010 periodically and am not sure how.
Basically there is a domain, domain.com, and a sub-domain, sub.domain.com, within the same Forest.
Exchange 2010 serves user/mailboxes in both domains.
When a user logs into the Outlook Web Access, we'd prefer them not have to manually type their domain each time (like domain\username, or sub-domain\username), but instead be easily able to login.
From what I understand the logon.aspx page or related files may need to be customized here:
C:\Program Files\Microsoft\Exchange Server\ClientAccess\Owa\auth
There are some duplicate usernames between the parent domain and child domain, so we can't have it just be the username because if it's "JSmith" and there's a "JSmith" in both domains, then it won't work.
So if they could have a radio button, or a drop-down menu, that lists "domain" or "sub-domain" which would prepend or append to the username box accordingly, I think that would be ideal.
Unless there's another way?
