Hi !

Prerequisites:
+ OPNsense must use AD DNS (do not use DNS from DHCP/WAN)
+ OPNsense must have a hostname in AD DNS (A and PTR)
+ OPNsense must be in sync with AD DNS time (use one IP of AD in NTP)
+ OPNsense must be in same domain as AD (hostname configuration page)
+ Create a new Authorization server with ssoproxyad type

Configuration:
+ Configure Single-Sign-On page with appropriate information
- Execute joinDomain button

Unable to create keytab: Error: ldap_sasl_interactive_bind_s failed (Unknown authentication method) additional info: SASL(-4): no mechanism available: No worthy mechs foundError: ldap_connect failed--> Is your kerberos ticket expired? You might try re-"kinit"ing.--> Is DNS configured correctly? You might try options "--server" and "--no-reverse-lookups".
