I have grabbed the 2.1.11 from git.freeradius.org, and unfortunally I get the same warning: Debug: WARNING: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Debug: WARNING: !! EAP session for state 0xc729a88ac72ab1dd did not finish! Debug: WARNING: !! Please read http://wiki.freeradius.org/Certificate_Compatibility Debug: WARNING: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I have tried with several EAP types, such PEAP-MSCHAPv2, TTLS, TLS with Windows, Cisco and Intel supplicants and always get the same warning. I always install the CA on Windows client, even the server.crt and server.p12 with no success. Has anyone face with this issue? Thanks a lot. -- View this message in context: http://freeradius.1045715.n5.nabble.com/freeradius-2-1-10-WARNING-Internal-s... Sent from the FreeRadius - User mailing list archive at Nabble.com.
