Hi, I've been trying to get machine auth working for a good while and I'm currently stuck trying to figure out why ntlm_auth is returning "No logon workstation trust account (0xc0000199)". I've double checked AD and the account definitely exists, and the machine has no problem logging into the domain. User auth works fine. Here's an example command: /usr/bin/ntlm_auth --request-nt-key --username=NOLP3003$ --domain=FOO --challenge=4a8904ffb0ba86d2 --nt-response=7ab480ea0a0754603629da316c9911935ff3c92daffcc621 No logon workstation trust account (0xc0000199) ntlm_auth is version 3.6.1-34.3.1-2691-SUSE-SL12.1-x86_64 Does anyone have any suggestions? I realise that this isn't really a Freeradius issue, but I'm hoping someone here has come across this before. Thanks in advance, Bryce
