How to import key vault access policies?

Trying to import multiple access policies into multiple key vaults in a Azure subscription.

I was able to get an export and populate to CSV exactly what I needed.

Problem I am having is on the import-csv foreach-object. Because Key vault requires comma separated values on the permissions keys, secrets and certificate it will not work with my command as its looking for a single variable.

Example. -PermissionsToKeys All,Get,Update

My PowerShell command.

Import-Csv -Path "C:\temp\kv-policies.csv" | ForEach-Object {
Set-AzKeyVaultAccessPolicy -VaultName $_.KeyVaultName -UserPrincipalName $_.UPN -PermissionsToCertificates $_.PermissionsToCertificatesStr -PermissionsToKeys $_.PermissionsToKeysStr -PermissionsToSecrets $_.PermissionsToSecretsStr}

Error

Set-AzKeyVaultAccessPolicy : Cannot validate argument on parameter 'PermissionsToCertificates'. The argument "string Substring(int startIndex), string Substring(int startIndex, int length)" does not belong to the set "all,get,list,delet e,create,import,update,managecontacts,getissuers,listissuers,setissuers,deleteissuers,manageissuers,recover,purge,backu p,restore" specified by the ValidateSet attribute. Supply an argument that is in the set and then try the command again. At line:2 char:112

I tried testing your scenario but as we are doing for multiple users and multiple permissions it’s a limitation to use Powershell to update the access policy . So, its recommended to use ARM template to assign multiple policies.

If its multiple users and single permission then you can use your Powershell script .

Step1: For adding Multiple access policies for users you will need to get the objectID for the users present in azure ad .

You can use use the CLI command :

az ad user show --id "upn" --query "objectId"

Step 2: Then you can use the below Template to add multiple access policies to a Keyvault .

    "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",

                        }
                    }
                ]
            }
       }
    ]
}

Step 4: Now Connect-Azaccount in Powershell and execute the template using below command.

New-AzResourceGroupDeployment -ResourceGroupName "keyvaultresourcegroup" -TemplateFile kvpolicies.json

It will ask you the keyvault Name and after providing it you will have successfully added the access policies to the Keyvault.

Output:
