Hello I have interesting problems with freeradius authentication. NAS - cisco 2801 radius - freeradius running on freebsd with mysql db. I had a lot of such errors in radius.log: Auth: Login incorrect (rlm_pap: CRYPT password check failed): [1-102/D\014\003\222\374\267<z\013y\005\200\354S\373\344] (from client plaza port 0) In debug output i get "unprintable characters". In the same time authentication was working fine from other hosts, for example smtp server. Problem was solved in interesting way, on cisco i specified radius source interface. It was working fine until mysql server crashed and i got same garbage in authentication. I removed source radius interface from cisco configuration and everything started to work fine again. Any ideas?
