Hi, I finally got freeradius to strip the host/ and append the $ to the host name, but it still wont validate the workstation. I get "No logon workstation trust account (0xc0000199)" At least now it's narrowed down to the ntlm_auth command. I tried to run the command manually with different workstation accounts, and got the same error. I know I've modified the code correctly by changing: init_id_info2(&ctr.auth.id2, domain, 0x800, /* param_ctrl */ 0xdead, 0xbeef, /* LUID? */ Any suggestions???
