You might want to do an LDAP lookup first on your UPN to find the samAccountName, then use that with ntlm_auth. Stefan From: freeradius-users-bounces+stefan.paetow=diamond.ac.uk@lists.freeradius.org [mailto:freeradius-users-bounces+stefan.paetow=diamond.ac.uk@lists.freeradius.org] On Behalf Of Angelica Delgado Sent: 14 October 2013 21:51 To: FreeRadius users mailing list Subject: configure freeradius to use UPN instead of samaccountname We have our freeradius setup to authenticate with Active Directory for EAP. Currently, it uses the samaccountname but we want to use UPN instead. We get "NT_STATUS_NO_SUCH_USER" when testing with ntlm through command line. ntlm_auth --request-nt-key --domain=test.local --username=tuser@pub.com<mailto:tuser@pub.com> Can you please let us know what needs to be configured to support the UPN?
