All, I am trying to authenticate my wifi users via our AD. I'm finding bits and pieces on the internet to configure things, but no completely usable howto. Can someone of the users look at the ouput below and point me to the correct solution/howto? I setup smb.conf,krb5.conf and freeradius. I joined the server to the domain and tested the connection with ntlm_auth: [root@belx11ke ~]# /usr/bin/ntlm_auth --request-nt-key --username=sstruyf --domain=KMT-EU.KMTG.NET password: NT_STATUS_OK: Success (0x0) [root@belx11ke ~]# rights of the winbind pipe: ls -l /var/cache/samba/winbindd_privileged total 0 srwxrwxrwx 1 root root 0 Oct 25 14:46 pipe below is the debug output of freeradius Processing the authenticate section of radiusd.conf modcall: entering group authenticate for request 7 rlm_eap: Request found, released from the list rlm_eap: EAP/peap rlm_eap: processing type peap rlm_eap_peap: Authenticate rlm_eap_tls: processing TLS eaptls_verify returned 7 rlm_eap_tls: Done initial handshake eaptls_process returned 7 rlm_eap_peap: EAPTLS_OK rlm_eap_peap: Session established.
