acl edit

Modifies a specific user's access to a cluster or volume.

The acl edit command grants one or more specific volume or cluster permissions to a user. To use the acl edit command, you must have administrative (a) permissions on the volume and cluster for which you are running the command. The permissions are specified as a comma-separated list of permission codes. See acl. You must specify either a user or a group. When the type is volume, a volume name must be specified using the name parameter.

Syntax

CLI

maprcli acl edit
    [ -cluster <cluster name> ]
    [ -group <group> ]
    [ -name <name> ]
    -type cluster|volume
    [ -user <user> ]

REST

http[s]://<host:port>/rest/acl/edit?<parameters>

Parameters

Parameter	Description
cluster	The cluster on which to run the command.
group	Groups and allowed actions for each group. See acl. Format: `<group>:<action>[,<action>...][ <group>:<action>[,<action...]]`
name	The object name.
type	The object type (`cluster` or `volume`).
user	Users and allowed actions for each user. See acl. Format: `<user>:<action>[,<action>...][ <user>:<action>[,<action...]]`

Examples

Give the user jsmith dump, restore, and delete permissions for "test-volume":

CLI

maprcli acl edit -type volume -name test-volume -user jsmith:dump,restore,d
