Created attachment 11040 [details] ntlm_auth passed a FQDN and a NT domain The --domain flag of ntlm_auth in version 4.1.17 worked with a FQDN. I have tested ntlm_auth in versions 4.2.0 and 4.2.1 with the --domain flag and now I find it only works with the non-AD domain names. (See attachment) Dovecot passes a FQDN to ntlm_auth instead of the non-AD NT domain; NTLM authentication is currently broken. Environment is Gentoo Linux with a 3.19.3 hardened kernel. gcc version 4.8.4 (Gentoo Hardened 4.8.4 p1.4, pie-0.6.1).
