Spec 12 S5: job directoryCheck (hourly) looks up every active user with a directory account;
one deleted, disabled there or no longer matched by the user filter is disabled here, sessions
ended. Nothing changes when the directory is unreachable or a run would disable most people;
the last admin with a password is kept; nobody is re-enabled. Dashboard warning
directory_check (system.directoryWarning). The by-id search is a filter object: ldapts string
filters send bytes >= 0x80 as UTF-8, so AD's objectGUID never matched. Live test against a
Samba 4 AD DC: nested-group admin, the disabled bit, objectGUID, a deleted user disabled.
Spec 12 S4: the login form checks the SelfPhoneNG password first, then the directory (ldapts,
service-account search, the user's own bind on a second connection). Presets for lldap, AD,
FreeIPA and OpenLDAP; Test with an optional test login. A directory account connects by email,
never makes a user; adminFilter sets the role (applyRole shared with OpenID). One Disconnect
route per kind (oidc, ldap). Live test against lldap 0.6.3 over LDAPS.
