* dirmngr/dirmngr.h (opts): Remove fields 'system_service' and 'system_daemon'. * common/homedir.c (dirmngr_sys_socket_name): Remove. (dirmngr_user_socket_name): Rename to ... (dirmngr_socket_name): this. Change call callers. * common/asshelp.c (start_new_dirmngr): Remove the system socket feature. * tools/gpgconf.c (list_dirs): Do not print "dirmngr-sys-socket". * sm/server.c (gpgsm_server): Adjust for removed system socket feature. * dirmngr/server.c (cmd_getinfo): Ditto. (cmd_killdirmngr): Remove check for system daemon. (cmd_reloaddirmngr): Ditto. * dirmngr/dirmngr.c (USE_W32_SERVICE): Remove macro. (aService): Remove. (opts): Remove --service. (w32_service_control): Remove. (real_main, call_real_main) [W32]: Remove wrapper. (main): Remove Windows system service feature. Remove system dameon feature. Use only the "~/.gnupg/dirmngr_ldapservers.conf" file. * dirmngr/certcache.c (load_certs_from_dir): Remove warning in the system dameon case. * dirmngr/crlcache.c (DBDIR_D): Always use "~/.gnupg/crls.d". * dirmngr/ocsp.c (validate_responder_cert): Do not call validate_cert_chain which was used only in system daemon mode. * dirmngr/validate.c (validate_cert_chain): Always use the code. -- We are now starting dirmngr as needed as a user daemon. The deprecated system daemon mode does not anymore make sense. In case a system wide daemon is required, it is better to setup a dedicated account to run dirmngr and tweak socket permissions accordingly. Signed-off-by: Werner Koch <wk@gnupg.org>
