Name mapping with System Manager - ONTAP 9.7 and earlier

Contributors netapp-maireadn netapp-aoife

You can use ONTAP System Manager classic (available in ONTAP 9.7 and earlier) to specify name mapping entries to map users from different platforms.

Name mapping conversion rules

An ONTAP system keeps a set of conversion rules for each 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 Mapping window

You can use the Name Mapping window to specify the name mapping entries to map users from different platforms.

Name Mappings

You can create and use name mappings to map your UNIX users to Windows users, Windows users to UNIX users, or Kerberos users to UNIX users.

Command buttons

  • Add

    Opens the Add Name Mapping Entry dialog box, which enables you to create a name mapping on storage virtual machines (SVMs).

  • Edit

    Opens the Edit Name Mapping Entry dialog box, which enables you to edit a name mapping on SVMs.

  • Delete

    Opens the Delete Name Mapping Entries dialog box, which enables you to delete a name mapping entry.

  • Swap

    Opens the Swap Name Mapping Entries dialog box, which enables you to interchange positions of the two selected name mapping entries.

  • Refresh

    Updates the information in the window.

Name mappings list

  • Position

    Specifies the name mapping’s position in the priority list. Name mappings are applied in the order in which they occur in the priority list.

  • Pattern

    Specifies the user name pattern that must be matched.

  • Replacement

    Specifies the replacement pattern for the user name.

  • Direction

    Specifies the direction of the name mapping. Possible values are krb_unix for a Kerberos-to-UNIX name mapping, win_unix for a Windows-to-UNIX name mapping, and unix_win for a UNIX-to-Windows name mapping.

Command buttons

  • Add

    Opens the Add Group Mapping Entry dialog box, which enables you to create a group mapping on SVMs.

  • Edit

    Opens the Edit Group Mapping Entry dialog box, which enables you to edit the group mapping on SVMs.

  • Delete

    Opens the Delete Group Mapping Entries dialog box, which enables you to delete a group mapping entry.

  • Swap

    Opens the Swap Group Mapping Entries dialog box, which enables you to interchange positions of the two selected group mapping entries.

  • Refresh

    Updates the information in the window.

Group mappings list

  • Position

    Specifies the group mapping’s position in the priority list. Group mappings are applied in the order in which they occur in the priority list.

  • Pattern

    Specifies the user name pattern that must be matched.

  • Replacement

    Specifies the replacement pattern for the user names.

  • Direction

    Specifies the direction of the group mapping. Possible values are krb_unix for a Kerberos-to-UNIX group mapping, win_unix for a Windows-to-UNIX group mapping, and unix_win for a UNIX-to-Windows group mapping.
