I have my preferred server set - no replica, no source. Read only credentials test successful. When I move to HII Driver Management -> Build Libary and put in my UNC path to my preferred server and select Save, I get:
"Access to the path \\preferredServer\driverLocation is denied. The specified user does not have adequate permissions to access the driver location."
So I'm thinking that the permission level is configured using the preferred server properties. Using Write credentials inside Preferred server properties I get:
"No sources have been selected to test credential against. At least one source must be selected"
Obviously, I'm missing something.
