I'm having trouble with certificates for my NAC environment. I have generated the CSR with the private key. I have then requested certificate from a Windows 2003 Server CA Authority. I'm not sure which item to use so I have tried with Administrator, Web Server and User. I download the certificate from the CA and try uploading to the CAM and always keep getting "Must include end entity". I'm not sure if I'm doing the whole process correctly seeing as there is not much information to using a Microsoft CA. Has any one done this and can give me a help.
