Hi, We migrated to 2.1.8 (from 2.1.7) last week while things were quiet, as the users have re-appeared after the holiday we've started to receive a few reports from users stating that they have been getting lots of prompts for credentials. Two users in particular, both Ubuntu users, have been having big problems. I had a look at the radpostauth table and sure enough at least 50% of their auth attempts have resulted in access-rejects. I rolled back to 2.1.7 this afternoon and the problem has gone away. Should anyone be interested I have attached an radmin output for one of the users, it shows some accepts and lots of rejects. Is this likely to be a configuration error (no changes were made to the 2.1.7 config), or a bug? Thanks, Jezz Palmer.
