NAME

idmapd.conf - configuration file for libnfsidmap  

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, initiated 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 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 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 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)
 

[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 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)
 

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

NAME

rpc.idmapd - NFSv4 ID <-> Name Mapper  

SYNOPSIS

rpc.idmapd [-h ] [-f ] [-v ] [-C ] [-S ] [-p path ] [-c path ]  

DESCRIPTION

rpc.idmapd is the NFSv4 ID <-> name mapping daemon. It provides functionality to the NFSv4 kernel client and server, to which it communicates via upcalls, by translating user and group IDs to names, and vice versa.

Note that on more recent kernels only the NFSv4 server uses . The NFSv4 client instead uses nfsidmap(8), and only falls back to rpc.idmapd if there was a problem running the nfsidmap(8) program.

The options are as follows:

-h
Display usage message.
-v
Increases the verbosity level (can be specified multiple times).
-f
Runs rpc.idmapd in the foreground and prints all output to the terminal.
-p path
Specifies the location of the RPC pipefs to be path The default value is "/var/lib/nfs/rpc_pipefs".
-c path
Use configuration file path
-C
Client-only: perform no idmapping for any NFS server, even if one is detected.
-S
Server-only: perform no idmapping for any NFS client, even if one is detected.

 

EXAMPLES

rpc.idmapd -f -vvv

Runs rpc.idmapd printing all messages to console, and with a verbosity level of 3.
