All- Unix background (years ago). Noob to Linux (vocab, tech, etc), no networking experience or background, noob to FreeRadius. This request concerns an issue I see often in the posts. Yet, for all the efforts made leveraging the posted answers, I have failed to resolve this common question. My assigned task was is to successfully install and configure the freeradius (2.2.6) for AAA Server and 802.1x review. At this stage I have installed it, and got it to reject all attempts to authenticate my test user. I have attached the output from the raddb -X server run in debug as well as the client side test user attempt using radtest. I have followed the "startup and test" recommendations that are in the freeradius website. I have modified (SIMPLY) the /etc/raddb/users file as recommended. I naively expected the server to authenticate with "Access-Accept". I have reset the users, raddb_conf and clients_conf files to the originals and run the same tests again. I have replaced the ipaddress for localhost with localhost. I have tried to insert with the user the companies NAS IP address which differs form the NAS ip set to localhost I see in some test basics examples online. I DO see the company's IPaddress for the NAS in the output of the debug run. Running as user "test", "testuser", etc. has failed (examples from online tutorials). I have even inserted user root and root password (thinking that authentication failed at bladeserver/CompanyNAS/freeradius server PAP tests. I am only trying to get this running using PAP at the moment (one challenge at a time). All attempts have failed to result in Access-Accept. All have returned Access-Rejected. At least it works there. One thing I have NOT done is set up a new client in the client.conf file. This is because I read over and over again that the basic setup should not be changed and it should run successfully during this basic PAP configuration test. I have checked and rechecked all (at least as far as I know) "known-good" passwords and they match (input and config files). I assume its not authenticating at the NAS. But when I set it up with root and root password as the user, that failed as well. I am afraid due to my lack of experience, I may not know what question SHOULD be asked to troubleshoot and successfully configure the freeradius/radtest testrun. I ask for your help, please. Thank you. From Server Run output (0) pap: WARNING: No "known good" password found for the user.
