I'm trying todo PEAP-MSCHAPv2 with authentication against an AD Currently I have the following problem: When the domain is in the username the authentication fails, if the domainname isn't in the authentication the authentication succeeds. I'm using the following ntlm_auth line in radiusd.conf: ntlm_auth = "/usr/bin/ntlm_auth --request-nt-key --username=%{Stripped-User-Name:-%{User-Name:-None}} --challenge=%{mschap:Challenge:-00} --nt-response=%{mschap:NT-Response:-00} --require-membership-of=S-1-5-21-3816208617-2573269785-2633524980-1134 --domain=%{mschap:NT-Domain:-IMZ}" The with_ntdomain_hack = yes is enabled in the mschap {} Output from shell: radius1:/etc/freeradius# /usr/bin/ntlm_auth --request-nt-key --username=IMZ\\beheerder --challenge=e456e008c25a9ac7 --nt-response=28e9d997b30267a36af64a4fcb530cd6b08f1141c09bc580 --require-membership-of=S-1-5-21-3816208617-2573269785-2633524980-1134 --domain=IMZ Logon failure (0xc000006d) radius1:/etc/freeradius# /usr/bin/ntlm_auth --request-nt-key --username=beheerder --challenge=e456e008c25a9ac7 --nt-response=28e9d997b30267a36af64a4fcb530cd6b08f1141c09bc580 --require-membership-of=S-1-5-21-3816208617-2573269785-2633524980-1134 --domain=IMZ NT_KEY: EB23807FB13B1CAB06F4F0BBE5C199D0 Debugging information (with a different user) Processing the authenticate section of radiusd.conf modcall: entering group authenticate for request 252 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.

Hi,
When the domain is in the username the authentication fails, if the domainname isn't in the authentication the authentication succeeds. I'm using the following ntlm_auth line in radiusd.conf:
you need to deal with your prefix (IMZ\\) - check the prefix section of the radiusd config - and make sure prefix is enabled in the auth sections. this should help deal with this issue alan
