I installed IBM Domino 9.1 and it is working internally. I have not set it up for Internet email yet, but it can send and receive messages internally. This server is Windows Server 2008 and it is a member of the domain.
I want to be able to access user accounts using Domino Web Access. So, in Internet Explorer, I entered the local URL of http://server.domain.com/mail/user.nsf to open up the user account. When I do this, I am prompted with a Windows Security warning saying, "The server ... at /mail requires a username and password." I entered in the Windows user name and password, but this warning keeps coming up. Eventually, IO receive an Error 401 error saying that I am not authorized to perform this operation.
Why am I getting prompted by Windows for logon credentials, and what credentials should I be using?
