Configuration file for libnfsidmap. Used by idmapd and svcgssd to map NFSv4 name to and from ids.
The idmapd.conf configuration file consists of several sections, initiated by strings of the form [General] and [Mapping]. Each section may contain lines of the formvariable = valueThe recognized sections and their recognized variables are as follows:
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: Hosts fully-qualified DNS domain name) Local-Realms A comma-separated list of Kerberos realm names that may be considered 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 hosts default realm name)
Note: If a value is specified here, the default local realm must be included as well.
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.
Method A comma-separated, ordered list of mapping methods (plug-ins) to use when mapping between NFSv4 names and local IDs. Each specified 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)
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
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 schemas attribute name to be used for NFSv4 user names (Default: NFSv4Name) NFSv4_uid_attr Your local schemas attribute name to be used for uidNumber (Default: uidNumber) GSS_principal_attr Your local schemas attribute name for GSSAPI Principal names (Default: GSSAuthName) NFSv4_acctname_attr Your local schemas 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 schemas attribute name to be used for gidNumber (Default: gidNumber) NFSv4_group_attr Your local schemas 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 minutes if there are thousands of groups. So setting LDAP_use_memberof_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)
An example /etc/idmapd.conf file:
Verbosity = 0 Domain = domain.org Local-Realms = DOMAIN.ORG,MY.DOMAIN.ORG,YOUR.DOMAIN.ORG
Nobody-User = nfsnobody Nobody-Group = nfsnobody
Method = umich_ldap,nsswitch GSS-Methods = umich_ldap,static
johndoe@OTHER.DOMAIN.ORG = johnny
LDAP_server = ldap.domain.org LDAP_base = dc=org,dc=domain
