# # Global configuration options. # # open_file_limit - set the maximum number of open files. Note there # may be other limits within the system that prevent # this from being set, systemd for example may need # a setting in the unit file to increase its default. # The autofs default is 20480. # #open_file_limit = 20480 # # # Define default options for autofs. # [ autofs ] # # master_map_name - default map name for the master map. # #master_map_name = auto.master # # timeout - set the default mount timeout in secons. The internal # program default is 10 minutes, but the default installed # configuration overrides this and sets the timeout to 5 # minutes to be consistent with earlier autofs releases. # timeout = 300 # # master_wait - set the default maximum number of retries (actual # iterations is half this, each is delayed by 2 seconds # before retrying) waiting for the master map to become # available if it cannot be read at program start # (default 10, then continue). This can be longer # if the map source itself waits for availability # (such as sss). # #master_wait = 10 # # negative_timeout - set the default negative timeout for # failed mount attempts (default 60). # #negative_timeout = 60 # # mount_verbose - use the -v flag when calling mount(8) and log some # process information about the requestor and its # parent. # #mount_verbose = no # # mount_wait - time to wait for a response from mount(8). # Setting this timeout can cause problems when # mount would otherwise wait for a server that # is temporarily unavailable, such as when it's # restarting. The default setting (-1) of waiting # for mount(8) usually results in a wait of around # 3 minutes. # #mount_wait = -1 # # umount_wait - time to wait for a response from umount(8). # #umount_wait = 12 # # browse_mode - maps are browsable by default. # browse_mode = no # # mount_nfs_default_protocol - set the default protocol that mount.nfs(8) # uses when performing a mount. Autofs needs # to know the default NFS protocol that # mount.nfs(8) uses so it can do special case # handling for its availability probe for # different NFS protocols. Since we can't # identify the default automatically we need # to set it in our configuration. # #mount_nfs_default_protocol = 3 mount_nfs_default_protocol = 4 # # append_options - append to global options instead of replace. # #append_options = yes # # logging - set default log level "none", "verbose" or "debug" # #logging = none # # force_standard_program_map_env - disable the use of the "AUTOFS_" # prefix for standard environemt variables when # executing a program map. Since program maps # are run as the privileded user this opens # automount(8) to potential user privilege # escalation when the program map is written # in a language that can load components from, # for example, a user home directory. # # force_standard_program_map_env = no # # use_mount_request_log_id - Set whether to use a mount request log # id so that log entries for specific mount # requests can be easily identified in logs # that have multiple concurrent requests. # #use_mount_request_log_id = no # # Define base dn for map dn lookup. # # Define server URIs # # ldap_uri - space seperated list of server uris of the form # <proto>://<server>[/] where <proto> can be ldap # or ldaps. The option can be given multiple times. # Map entries that include a server name override # this option. # # This configuration option can also be used to # request autofs lookup SRV RRs for a domain of # the form <proto>:///[<domain dn>]. Note that a # trailing "/" is not allowed when using this form. # If the domain dn is not specified the dns domain # name (if any) is used to construct the domain dn # for the SRV RR lookup. The server list returned # from an SRV RR lookup is refreshed according to # the minimum ttl found in the SRV RR records or # after one hour, whichever is less. # #ldap_uri = "" # # ldap_timeout - timeout value for the synchronous API calls # (default is LDAP library default). # #ldap_timeout = -1 # # ldap_network_timeout - set the network response timeout (default 8). # #ldap_network_timeout = 8 # # search_base - base dn to use for searching for map search dn. # Multiple entries can be given and they are checked # in the order they occur here. # #search_base = "" # # Define the LDAP schema to used for lookups # # If no schema is set autofs will check each of the schemas # below in the order given to try and locate an appropriate # basdn for lookups.

That produces, IMHO, # unnecessary noise in the log so a configuration option # has been added to provide the ability to turn it off. # The default is "no" to maintain the current behaviour. # #disable_not_found_message = "no" # # use_ignore_mount_option - This option is used to enable the use of autofs # pseudo option "ignore". This option is used as a # hint to user space that the mount entry should be # ommitted from mount table listings. The default is # "no" to avoid unexpected changes in behaviour and # is an opt-in setting. # #use_ignore_mount_option = no # # sss_master_map_wait - When sssd is starting up it can sometimes return # "no such entry" for a short time until it has read # in the LDAP map information. Internal default is 0 # (don't wait) or 10 if sss supports returning EHOSTDOWN. # If there is a problem with autofs not finding the # master map at startup (when it should) then try setting # this to 10 or more. If the sss library supports returning # EHOSTDOWN when the provider is down then this value # is how long to wait between retries reading the # master map. When reading dependent maps or looking # up a map key this value is multiplied by the number # of retries that would be used when reading the master # map. (Default, 0 or 10 if sss suppprts returning # EHOSTDOWN). # #sss_master_map_wait = 0 # # Options for the amd parser within autofs. # # amd configuration options that are aren't used, haven't been # implemented or have different behaviour within autofs. # # A number of the amd configuration options are not used by autofs, # some because they are not relevant within autofs, some because # they are done differently in autofs and others that are not yet # implemented. # # Since "mount_type" is always autofs (because there's no user space # NFS server) the configuration entries relating to that aren't used. # Also, server availability is done differently within autofs so the # options that relate to the amd server monitoring sub-system are # also not used. # # These options are mount_type, auto_attrcache, portmap_program, # nfs_vers_ping, nfs_allow_any_interface, nfs_allow_insecure_port, # nfs_proto, nfs_retransmit_counter, nfs_retransmit_counter_udp, # nfs_retransmit_counter_tcp, nfs_retransmit_counter_toplvl, # nfs_retry_interval, nfs_retry_interval_udp, nfs_retry_interval_tcp, # nfs_retry_interval_toplvl and nfs_vers. # # # Other options that are not used within the autofs implementation: # # log_file, truncate_log - autofs used either stderr when running in # the foreground or sends its output to syslog so an alternate # log file (or truncating the log) can't be used. # # print_pid - there's no corresponding option for this within autofs. # # use_tcpwrappers, show_statfs_entries - there's no user space NFS # server to control access to so this option isn't relevant. # The show_statfs_entries can't be implemented for the same # reason. # # debug_mtab_file - there's no user space NFS server and autofs # avoids using file based mtab whenever possible. # # sun_map_syntax - obviously, are provided by autofs itself. # # plock, show_statfs_entries, preferred_amq_port - not supported. # # ldap_cache_maxmem, ldap_cache_seconds - external ldap caching # is not used by autofs. # # ldap_proto_version - autofs always attempts to use the highest # available ldap protocol version. # # cache_duration, map_reload_interval, map_options - the map # entry cache is continually updated and stale entries # cleaned on re-load, which is done when map changes are # detected so these configuration entries are not used # by autofs. # # localhost_address - is not used within autofs. This # configuration option was only used in the amd user # space server code and is not relevant within autofs. # # # Options that are handled differently within autofs: # # pid_file - must be given as a command line option on startup. # # print_version - program version and feature information is obtained # by using the automount command line option "-V". # # debug_options, log_options - autofs has somewhat more limited # logging and debug logging options. When the log_options # options is encountered it is converted to the nearest # matching autofs logging option. Since the configuration # option debug_options would be handled the same way it # is ignored. # # restart_mounts - has no sensible meaning within autofs because autofs # always tries to re-connect to existing mounts. While this # has its own set of problems not re-connecting to existing # mounts always results in a non-functional automount tree if # mounts were busy at the last shutdown (as is also the case # with amd when using mount_type autofs). # # forced_unmounts - detaching mounts often causes serious problems # for users of existing mounts. It is used by autofs in some # cases, either at the explicit request of the user (with a # command line or init option) and in some special cases during # program operation but is avoided whenever possible. # # # A number of configuration options are not yet implemented: # # fully_qualified_hosts - not yet implemented. # # unmount_on_exit - since autofs always tries to re-connect # to mounts left mounted from a previous shutdown this # is a sensible option to implement and that will be # done. # # exec_map_timeout - a timeout is not currently used for # for program maps, might be implemented. # # tag - the tag option is not implemented within autofs. # # # Supported options: # # arch, karch, os, osver - these options default to what is returned # from uname(2) and can be overridden if required. # # full_os - has no default and must be set in the configuration # if used in maps. # # cluster - if not set defaults to the host domain name. This option # corresponds to the HP_UX cluster name (according to the amd # source) and is probably not used in Linux but is set anyway. # # vendor - has a default value of "unknown", it must be set in the # configuration if used in maps. # # auto_dir - is the base name of the mount tree used for external # mounts that are sometimes needed by amd maps. Its default # value is "/a". # # map_type - specifies the autofs map source, such as file, nis, # ldap etc. and has no default value set. # # map_defaults - is used to override /defaults entries within maps # and can be used to provide different defaults on specific # machines without having to modify centrally managed maps. # It is empty by default. # # search_path - colon seperated paths to search for maps that # are not specified as a full path. # # dismount_interval - is equivalent to the autofs timeout option. It # is only possible to use this with type "auto" mounts due # to the way the autofs kernel module performs expiry. It # takes its default value from the autofs internal default # of 600 seconds. # # browsable_dirs - make map keys visible in directory listings. # Note that support for the "fullybrowsable" option cannot # be added using the existing kernel to user space autofs # implementation. # # autofs_use_lofs - if set to "yes" autofs will attempt to use bind # mounts for type "link" entries when possible. # # nis_domain - allows setting of a domain name other than the system # default. # # local_domain - is used to override (or set) the host domain name. # # normalize_hostnames - if set to "yes" then the contents of ${rhost} # is translated in its official host name. # # domain_strip - if set to "yes" the domain name part of the host # is strippped when normalizing hostnames. This can be useful # when using of the same maps in a multiple domain environment. # # normalize_slashes - is set to "yes" by default and will collapse # multiple unescaped occurrences of "/" to a single "/". # # selectors_in_defaults, selectors_on_default - has a default value # of "no". If set to "yes" then any defaults entry will be # checked for selectors to determine the values to be used. # selectors_in_defaults is the preferred option to use. # # ldap_base - has no default value. It must be set to the base dn # that is used for queries if ldap is to be used as a map # source. # # ldap_hostports - has no default value set. It must be set to # the URI of the LDAP server to be used for lookups when # ldap is used a map source. It may contain a comma or # space seperated list of LDAP URIs. # # hesiod_base - the base name used for hesiod map sources. # # Additional configuration options added: # # linux_ufs_mount_type - set the default system filesystem type that's # used for mount type ufs. There's no simple way to determine # what the system default filesystem is and am-utils needs to # be continually updated to do this and can easily get it wrong # anyway. # # # Define global options for the amd parser within autofs. # [ amd ] # # Override the internal default with the same timeout that # is used by the override in the autofs configuration, sanity # only change. # dismount_interval = 300 # # map_type = file # # Overriding this can cause autofs to use less resources because # it will use symlinks instead of bind mounts in certain cases. # You should ensure that the autofs kernel module your using # supports expration of symlinks for best results (although this # appears to work reasonably well most of the time without the # update). # #autofs_use_lofs = yes # # Several configuration options can be set per mount point. # In particular map_type, map_name, map_defaults, search_path, # browsable_dirs, dismount_interval and selectors_in_defaults # (not all of which are currently implemented, see above). # # Also, if a section for an amd mount point is defined here # it isn't necessary to specify the format in the corresponding # master map entry and the format will be inherited for type # "auto" mounts. # #[ /example/mount ] #dismount_interval = 60 #map_type = nis
