NAME
       idmapd.conf

SYNOPSIS
       Configuration  file for libnfsidmap.  Used by idmapd and svcgssd to map
       NFSv4 name to and from ids.

DESCRIPTION
       The idmapd.conf configuration file consists of several sections, initi‐
       ated  by strings of the form [General] and [Mapping].  Each section may
       contain lines of the form
	 variable = value
       The recognized sections and their recognized variables are as follows:

   [General] section variables
       Verbosity
	      Verbosity level of debugging (Default: 0)

       Domain The local NFSv4 domain name.  An NFSv4  domain  is  a  namespace
	      with   a	unique	username<->UID	and  groupname<->GID  mapping.
	      (Default: Host's fully-qualified DNS domain name)

       Local-Realms
	      A comma-separated list of Kerberos realm names that may be  con‐
	      sidered  equivalent to the local realm name.  For example, users
	      juser@ORDER.EDU and juser@MAIL.ORDER.EDU may be considered to be
	      the  same	 user  in  the specified Domain.  (Default: the host's
	      default realm name)
	      Note: If a value is specified here, the default local realm must
	      be included as well.

   [Mapping] section variables
       Nobody-User
	      Local user name to be used when a mapping cannot be completed.

       Nobody-Group
	      Local group name to be used when a mapping cannot be completed.

   [Translation] section variables
       Method A comma-separated, ordered list of mapping methods (plug-ins) to
	      use when mapping between NFSv4 names and local IDs.  Each speci‐
	      fied method is tried in order until a mapping is found, or there
	      are no more methods to try.  The methods included in the default
	      distribution  include  "nsswitch",  "umich_ldap",	 and "static".
	      (Default: nsswitch)

       GSS-Methods
	      An optional comma-separated, ordered  list  of  mapping  methods
	      (plug-ins)  to  use when mapping between GSS Authenticated names
	      and local IDs.  (Default: the same list as specified for Method)

   [Static] section variables
       The "static" translation method uses a static list of GSS-Authenticated
       names to local user names.  Entries in the list are of the form:
	principal@REALM = localusername

   [UMICH_SCHEMA] section variables
       If  the	"umich_ldap"  translation  method  is specified, the following
       variables within the [UMICH_SCHEMA] section are used.

       LDAP_server
	      LDAP server name or address (Required if using UMICH_LDAP)

       LDAP_base
	      Absolute LDAP search base.  (Required if using UMICH_LDAP)

       LDAP_people_base
	      Absolute LDAP search base for people  accounts.	(Default:  The
	      LDAP_base value)

       LDAP_group_base
	      Absolute	LDAP  search  base  for group accounts.	 (Default: The
	      LDAP_base value)

       LDAP_canonicalize_name
	      Whether or not to perform	 name  canonicalization	 on  the  name
	      given as LDAP_server (Default: "true")

       LDAP_use_ssl
	      Set  to "true" to enable SSL communication with the LDAP server.
	      (Default: "false")

       LDAP_ca_cert
	      Location of a trusted CA certificate used when  SSL  is  enabled
	      (Required if LDAP_use_ssl is true)

       NFSv4_person_objectclass
	      The  object  class  name	for people accounts in your local LDAP
	      schema (Default: NFSv4RemotePerson)

       NFSv4_name_attr
	      Your local schema's attribute name to be	used  for  NFSv4  user
	      names (Default: NFSv4Name)

       NFSv4_uid_attr
	      Your  local  schema's  attribute	name  to be used for uidNumber
	      (Default: uidNumber)

       GSS_principal_attr
	      Your local schema's attribute name for  GSSAPI  Principal	 names
	      (Default: GSSAuthName)

       NFSv4_acctname_attr
	      Your  local schema's attribute name to be used for account names
	      (Default: uid)

       NFSv4_group_objectclass
	      The object class name for group  accounts	 in  your  local  LDAP
	      schema (Default: NFSv4RemoteGroup)

       NFSv4_gid_attr
	      Your  local  schema's  attribute	name  to be used for gidNumber
	      (Default: gidNumber)

       NFSv4_group_attr
	      Your local schema's attribute name to be used  for  NFSv4	 group
	      names (Default: NFSv4Name)

       LDAP_use_memberof_for_groups
	      Some  LDAP servers do a better job with indexing where searching
	      through all the groups searching for the user in	the  memberuid
	      list.   Others  like SunOne directory that search can takes min‐
	      utes if there are thousands of groups. So setting	 LDAP_use_mem‐
	      berof_for_groups	to true in the configuration file will use the
	      memberof lists of the account  and  search  through  only	 those
	      groups to obtain gids.  (Default: false)

       NFSv4_member_attr
	      If  LDAP_use_memberof_for_groups	is true, this is the attribute
	      to be searched for.  (Default: memberUid)

       NFSv4_grouplist_filter
	      An optional search filter for determining group membership.  (No
	      Default)

       LDAP_timeout_seconds
	      Number of seconds before timing out an LDAP request (Default: 4)

EXAMPLES
       An example /etc/idmapd.conf file:

       [General]

       Verbosity = 0
       Domain = domain.org
       Local-Realms = DOMAIN.ORG,MY.DOMAIN.ORG,YOUR.DOMAIN.ORG

       [Mapping]

       Nobody-User = nfsnobody
       Nobody-Group = nfsnobody

       [Translation]

       Method = umich_ldap,nsswitch
       GSS-Methods = umich_ldap,static

       [Static]

       johndoe@OTHER.DOMAIN.ORG = johnny

       [UMICH_SCHEMA]

       LDAP_server = ldap.domain.org
       LDAP_base = dc=org,dc=domain
