I am using Prime Infrastructure 1.4 and I am needing to set up RADIUS Authencation. I am using Microsoft Network Policy Server. I have done all of the setup on both systems. I have matched up the settings the best I can on both systems. I am trying to use CHAP. I keep getting username or passwrod is not valid. In a effort to test I changed the Authentication type to PAP (I do not want to use this because it is not encrypted) But in a effort of testing I changed the setting on both the NPS and on Prime. I am now able to log in. Changing back to CHAP it fails and states the Username or Password is invalid. SO, PLEASE HELP!!!!
