Overview

Name mapping is used to map CIFS identities to UNIX identities, Kerberos identities to UNIX identities, and UNIX identities to CIFS identities. It needs this information to obtain user credentials and provide proper file access regardless of whether they are connecting from an NFS client or a CIFS client.
The system keeps a set of conversion rules for each Storage Virtual Machine (SVM). Each rule consists of two pieces: a pattern and a replacement. Conversions start at the beginning of the appropriate list and perform a substitution based on the first matching rule. The pattern is a UNIX-style regular expression. The replacement is a string containing escape sequences representing subexpressions from the pattern, as in the UNIX sed program.
Name mappings are applied in the order in which they occur in the priority list; for example, a name mapping that occurs at position 2 in the priority list is applied before a name mapping that occurs at position 3. Each mapping direction (Kerberos-to-UNIX, Windows-to-UNIX, and UNIX-to-Windows) has its own priority list. You are prevented from creating two name mappings with the same pattern.

Examples

Use the following API to create a name-mapping. Note the return_records=true query parameter is used to obtain the newly created entry in the response.

# The API:

curl -X POST "https://<mgmt-ip>/api/name-services/name-mappings?return_records=true" -H "accept: application/json" -H "Content-Type: application/json" -d "{ \"client_match\": \"10.254.101.111/28\", \"direction\": \"win_unix\", \"index\": 1, \"pattern\": \"ENGCIFS_AD_USER\", \"replacement\": \"unix_user1\", \"svm\": { \"name\": \"vs1\", \"uuid\": \"f71d3640-0226-11e9-8526-000c290a8c4b\" }}"

Classes

class NameMapping (*args, **kwargs)

Name mapping is used to map CIFS identities to UNIX identities, Kerberos identities to UNIX identities, and UNIX identities to CIFS identities. It needs this information to obtain user credentials and provide proper file access regardless of whether they are connecting from an NFS client or a CIFS client.

Initialize the instance of the resource.

Any keyword arguments are set on the instance as properties. For example, if the class was named 'MyResource', then this statement would be true:

MyResource(name='foo').name == 'foo'

Args

*args
Each positional argument represents a parent key as used in the URL of the object. That is, each value will be used to fill in a segment of the URL which refers to some parent object. The order of these arguments must match the order they are specified in the URL, from left to right.
**kwargs
each entry will have its key set as an attribute name on the instance and its value will be the value of that attribute.

Class variables

var client_match

Client workstation IP Address which is matched when searching for the pattern. You can specify the value in any of the following formats:

  • As an IPv4 address with a subnet mask expressed as a number of bits; for instance, 10.1.12.0/24
  • As an IPv6 address with a subnet mask expressed as a number of bits; for instance, fd20:8b1e:b255:4071::/64
  • As an IPv4 address with a network mask; for instance, 10.1.16.0/255.255.255.0
  • As a hostname

Example: 10.254.101.111/28

var direction

Direction in which the name mapping is applied. The possible values are:

  • krb_unix - Kerberos principal name to UNIX user name
  • win_unix - Windows user name to UNIX user name
  • unix_win - UNIX user name to Windows user name mapping

Valid choices:

  • win_unix
  • unix_win
  • krb_unix
var index

Position in the list of name mappings.

Example: 1

The links field of the name_mapping.

var opts
var pattern

Pattern used to match the name while searching for a name that can be used as a replacement. The pattern is a UNIX-style regular expression. Regular expressions are case-insensitive when mapping from Windows to UNIX, and they are case-sensitive for mappings from Kerberos to UNIX and UNIX to Windows.

Example: ENGCIFS_AD_USER

var replacement

The name that is used as a replacement, if the pattern associated with this entry matches.

Example: unix_user1

var svm

The svm field of the name_mapping.
