Authentication: Azure

Use dsv config auth-provider search -e yaml to see all of your current authentication providers.

Initially, the only authentication provider is Thycotic One, similar to this:

Copy 
created: "2019-11-11T20:29:20Z"
createdBy: users:thy-one:admin@company.com
id: xxxxxxxxxxxxxxxxxxxx
lastModified: "2020-05-18T03:58:15Z"
lastModifiedBy: users:thy-one:admin@company.com
name: thy-one
properties:
 baseUri: https://login.thycotic.com/
 clientId: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
 clientSecret: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
type: thycoticone
version: "0"

Azure Authentication Provider

To add an Azure account to act as an authentication provider:

  • dsv config auth-provider create --name <name> --type azure --azure-tenant-id <Azure tenant ID>

where:

  • name is the friendly name used in VP-DV to reference this provider
  • type is the authentication provider type; in this case, azure
  • the property flag for Azure is --azure-tenant-id

To view the resulting addition to the config file, you would use:

dsv config auth-provider <name> read -e yaml where the example name we will use here is azure-prod

The readout would look similar to this:

Copy 
created: "2019-11-12T18:34:49Z"
createdBy: users:thy-one:admin@company.com
-id: xxxxxxxxxxxxxxxxxxxxx
lastModified: "2020-05-18T03:58:15Z"
lastModifiedBy: users:thy-one:admin@company.com
name: azure-prod
properties:
 tenantId: xxxxxxxxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
type: azure
version: "0"

Azure User Assigned MSI Example

First you will need to configure the User that corresponds to an Azure User Assigned MSI.

The username is a friendly name within VP-DV. It does not have to match the MSI username, but the provider must match the resource id of the MSI in Azure.

Copy 
dsv user create --username test-api --provider azure-prod --external-id /subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourcegroups/build/providers/Microsoft.ManagedIdentity/userAssignedIdentities/test-api

Modify the config to give that User access to the default administrator permission policy.

Adding a user to the admin policy is not security best practices. This is for example purposes only. Ideally, you would create a separate policy for this Azure user with restricted access. For details on limiting access through policies, see the Policy section.

dsv config edit --encoding yaml

Add the User as a subject to the Default Admin Policy. Third party accounts must be prefixed with the provider name; in this case the fully qualified username will be azure-prod:test-api.

Copy 
<snip>
- actions:
 - <.*>
 conditions: {}
 description: Default Admin Policy
 effect: allow
 id: xxxxxxxxxxxxxxxxxxxx
 meta: null
 resources:
 - <.*>
 subjects:
 - users:<azure-prod:test-api|admin@company.com>
<snip>

On a VM in Azure that has the User MSI assigned as the identity, download the DVS CLI executable appropriate to the OS of the VM and initialize the CLI.

Copy 
dsv init

When prompted for the authorization type, choose the Azure (federated) authentication option.

Copy 
Please enter auth type:
       (1) Password (local user)(default)
       (2) Client Credential
       (3) #{ThycoticOne}# (federated)
       (4) AWS IAM (federated)
       (5) Azure (federated)
       (6) GCP (federated)
       (7) OIDC (federated)

Read an existing secret to verify you can authenticate and access data.

Copy 
dsv secret read --path <path to a secret>

Azure Resource Group

If you want to grant access to a set of VMs in a resource group that use a System assigned MSI rather than a User assigned MSI, you can create a role that corresponds to the resource group's resource ID.

Copy 
dsv role create --name identity-rg  --external-id /subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourcegroups/build --provider azure-prod

Modify the config to give that role access to the default administrator permission policy.

Adding a role to the admin policy is not security best practices. This is for example purposes only. Ideally, you would create a separate policy for this Azure role with restricted access. For details on limiting access through policies, see the Policy section.

Copy 
dsv config edit --encoding yaml

Add the User as a subject to the Default Admin Policy. Third party accounts must be prefixed with the provider name; in this case the fully qualified role name will be azure-prod:identity-rg.

Copy 
<snip>
- actions:
 - <.*>
 conditions: {}
 description: Default Admin Policy
 effect: allow
 id: bgn8gjei66jc7148d9i0
 meta: null
 resources:
 - <.*>
 subjects:
 - users:<azure-prod:test-api|admin@company.com>
 - roles:<azure-prod:identity-rg>
<snip>

On a VM in Azure that is part of the resource group and has a system-assigned MSI, download the DVS CLI executable appropriate to the OS of the VM and initialize the CLI.

Copy 
dsv init

When prompted for the authorization type, choose the Azure (federated) option.

Copy 
Please enter auth type:
       (1) Password (local user)(default)
       (2) Client Credential
       (3) #{ThycoticOne}# (federated)
       (4) AWS IAM (federated)
       (5) Azure (federated)
       (6) GCP (federated)

Read an existing secret to verify you are able to authenticate and access data.

Copy 
dsv secret read --path <path to a secret>
