I am working with a chemical company with very tight security on their web servers. We have been testing MC9190 using PEAP authentication to get on the network and that is working as expected. The problem we encounter is that none of the web servers will permit is to connect. I spoke with the security group and that advised that the client (PC or Mobile Computer) must be authenticated to Active Directory. I'm a novice when it comes to Micriosoft security. The explanation the customer provided was that when a client is authenticated to Active Directory the client recieves a token/cert which includes the permissions assigned to the user in Active Directory. The server checks these credentials before permitting the uses access to the server I'd be interested in anyone who is currently working with one of our Mobile Computers in this type of environment and any details on the configuration required
