Set-AzDataLakeGen2ItemAclObject

Creates/Updates a DataLake gen2 item ACL object, which can be used in Update-AzDataLakeGen2Item cmdlet.

Syntax

Set-AzDataLakeGen2ItemAclObject
   [-EntityId <String>]
   [-DefaultScope]
   -Permission <String>
   [-InputObject <PSPathAccessControlEntry[]>]
   -AccessControlType <AccessControlType>
   [<CommonParameters>]

Description

The Set-AzDataLakeGen2ItemAclObject cmdlet creates/updates a DataLake gen2 item ACL object, which can be used in Update-AzDataLakeGen2Item cmdlet. If the new ACL entry with same AccessControlType/EntityId/DefaultScope not exist in the input ACL, will create a new ACL entry, else update permission of existing ACL entry.

Examples

Example 1: Create an ACL object with 3 ACL entry, and update ACL on a directory

$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType user -Permission rwx -DefaultScope
$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType group -Permission rw- -InputObject $acl 
$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType other -Permission "rw-" -InputObject $acl
Update-AzDataLakeGen2Item -FileSystem "filesystem1" -Path "dir1/dir3" -ACL $acl

FileSystem Name: filesystem1

Path                 IsDirectory  Length          LastModified         Permissions  Owner                Group               
----                 -----------  ------          ------------         -----------  -----                -----

This command creates an ACL object with 3 ACL entries (use -InputObject parameter to add acl entry to existing acl object), and updates ACL on a directory.

Example 2: Create an ACL object with 4 ACL entries, and update permission of an existing ACL entry

$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType user -Permission rwx -DefaultScope
$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType group -Permission rw- -InputObject $acl 
$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType other -Permission "rwt" -InputObject $acl
$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType user -EntityId $id -Permission rwx -InputObject $acl 
$acl

DefaultScope AccessControlType EntityId                             Permissions
------------ ----------------- --------                             -----------
True         User                                                   rwx        
False        Group                                                  rw-        
False        Other                                                  rwt        
False        User              ********-****-****-****-************ rwx        

$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType user -EntityId $id -Permission r-x -InputObject $acl 
$acl  

DefaultScope AccessControlType EntityId                             Permissions
------------ ----------------- --------                             -----------
True         User                                                   rwx        
False        Group                                                  rw-        
False        Other                                                  rw-        
False        User              ********-****-****-****-************ r-x

This command first creates an ACL object with 4 ACL entries, then run the cmdlet again with different permission but same AccessControlType/EntityId/DefaultScope of an existing ACL entry. Then the permission of the ACL entry is updated, but no new ACL entry is added.

Parameters

-AccessControlType

There are four types: "user" grants rights to the owner or a named user, "group" grants rights to the owning group or a named group, "mask" restricts rights granted to named users and the members of groups, and "other" grants rights to all users not found in any of the other entries.

Set this parameter to indicate the ACE belongs to the default ACL for a directory; otherwise scope is implicit and the ACE belongs to the access ACL.

Type:SwitchParameter
Position:Named
Default value:None

The user or group identifier. It is omitted for entries of AccessControlType "mask" and "other". The user or group identifier is also omitted for the owner and owning group.

If access is not granted, the '-' character is used to denote that the permission is denied. The sticky bit is also supported and its represented either by the letter t or T in the final character-place depending on whether the execution bit for the others category is set or unset respectively, absence of t or T indicates sticky bit not set.
