Integrate Okta IdP with Aviatrix controller

In this blog, I will show you step by step integrating Okta IdP (identity provider) with Aviatrix controller.

Okta configuration

First sign up with okta. In this example, I’m signing up as a developer account:
https://developer.okta.com/signup/
I’ve chosen to continue with my google account

Once logged in, Applications -> Applications -> Create App Integration

Choose SAML 2.0 as Sign-in method

Provide App name, such as Aviatrix
App logo is optional, and leave App visibility unchecked

In SAML settings

  • General

FieldValue

Single sign on URL https://[host]/flask/saml/sso/[Endpoint Name]
Audience URI (SP Entity ID) https://[host]/
Default RelayState https://[host]/#/dashboard
Name ID format Unspecified
Application username Okta username
Update application username on Create and update

[host] is the hostname or IP of your Aviatrix controller.

[Endpoint Name] is an arbitrary identifier. This same value should be used when configuring SAML in the Aviatrix controller. The example uses aviatrix_saml_controller for [Endpoint Name]

https://[host]/#/dashboard must be set as the Default RelayState so that after SAML authenticates, user will be redirected to dashboard.

  • Attribute Statements

NameName formatValue

FirstName Unspecified user.firstName
LastName Unspecified user.lastName
Email Unspecified user.email

In following example:
[host] = 22.2.2.2
[Endpoint Name] = aviatrix_saml_controller

Pick *anything* for feedback

In the newly created Aviatrix App Integration, scroll down to bottom, notice SHA-V2 is Active, click on it’s right side Actions drop down -> View IdP metadata

In newly opened browser window, copy the link, it would have following format. Save this link for next step.

https://dev-<accountid>.okta.com/app/<idstring>/sso/saml/metadata

 

Copy

 

Aviatrix Controller Configuration

Log into Aviatrix controller, eg: https:/22.2.2.2, you will be greeted with login for local account

After login, check user profile, shows as User: admin, which means you are using a local Aviatrix controller account logged in.

Settings -> Controller -> SAML Login -> Add new

Endpoint Name aviatrix_saml_controller Note: as we used earlier in Okta
IDP Metadata Type URL  
IDP Metadata URL https://dev-<accountid>.okta.com/
app/<idstring>/sso/saml/metadata
Note: As recorded earlier
Entity ID Hostname  
Access set by Controller  
RBAC Groups admin

Note: Permission assigned to this endpoint

Once the SAML Endpoints have been created, click on Test button

You will be greeted by this. As I did already login to Okta as my gmail account, however, I didn’t assign my gmail to Aviatrix application in Okta

Switch back to Okta -> Aviatrix application -> Assignments -> Assign -> Assign to People -> Selected my google account.

Goes back to Aviatrix SAML Endpoints page, and run Test again. The screen gets redirected, and you may see your email flash by

You can see your login indicates admin:<email> , which means SAML is working.

 

If you choose Sign out, it will return to login screen, notice that in the bottom, it listed the endpoint name: aviatrix_saml_controller we created earlier. Below it have a button to Sign in as SAML using this endpoint.

While this is working, since each endpoint is now mapping to a permission group defined in the Aviatrix controller, this would means for each permission group we have to create it’s own endpoint. People have to select a permission group from the drop down box before entering their login information, not very convenient.

Let’s take a look how we can utilize SAML IDP attribute to make this experience easier for end users.

Use SAML IDP attribute

Summary:

  1. Modify Aviatrix Controller SAML Endpoints to use SAML IDP attribute
  2. Create permission group, eg AWS_UsefulTools, assign it with permissions and access accounts
  3. In Okta, add additional directory attribute (eg aviatrixPermissionGroup) for user profile, so it can be used to match Aviatrix permission group
  4. In Okta, add this additional attribute (eg aviatrixPermissionGroup) to Aviatrix App SAML integration
  5. In Okta, add user profile with this additional directory attribute. (eg aviatrixPermissionGroup)
  6. Validation

Modify Aviatrix Controller SAML Endpoints to use SAML IDP attribute

Settings -> Controller -> SAML Login -> Select the SAML endpoint aviatrix_saml_controller created earlier, then choose Edit

Switch Access set by from Controller to SAML IDP attribute, then click OK

Create permission group, eg AWS_UsefulTools, assign it with permissions and access accounts

Let’s create a permission group: AWS_UsefulTools, let’s say this permission group will only have access to an AWS access account, and only have permission to Useful Tools section

Select the newly created AWS_UsefulTools permission group, click on Manage Permission, check “Useful Tools“, then click OK

Select the newly created AWS_UsefulTools permission group, click on Manage Access Accounts, check the AWS account to grant access, then click OK

Now this AWS_UsefulTools permission group can only perform Useful Tools operation with selected AWS account.

In Okta, add additional directory attribute (aviatrixPermissionGroup) for user profile, so it can be used to match Aviatrix permission group

In Okta, we need to make sure each Okta user account using Aviatrix application would have a custom attribute, let’s call it aviatrixPermissionGroup

Okta -> Directory -> Profile Editor -> Users -> Apps -> Locate the Aiviatrix app created earlier, since it’s related to Users, click on it’s name Aviatrix User

Click on Add attribute

Leave data type as string, make sure variable name is aviatrixPermissionGroup, and fill in corresponding Display name and Description

Now we have additional custom attribute aviatrixPermissionGroup created for each Okta users using Aviatrix application

In Okta, add this additional attribute (aviatrixPermissionGroup) to Aviatrix App SAML integration

Next we need to make sure Aviatrix application pass this custom attribute
Okta -> Applications -> Applications -> Find and click on Aviatrix application

General tab -> SAML Settings -> Edit -> 1 General Settings -> Next

2 Configure SAML -> Attribute Statements (optional), previously we have:

Click Add Another

Name Name format Value
Profile Unspecified

appuser.aviatrixPermissionGroup

Remember to click Next and Finish to complete SAML Settings change

In Okta, add user profile with this additional directory attribute. (aviatrixPermissionGroup)

Now we have to add user, and make sure this custom attribute would

Okta -> Directory -> People -> Add person

Then click on the user just created, it will be in pending status. Click on Set Password & Activate, a temporary password will be generated for next login

Applications -> Assigned Applications -> Assign Application

Assign Aviatrix application

In the customized profile field “Aviatrix Permission Group”, add AWS_UsefulTools permission group we created earlier in Aviatrix permission group.

Validation

Login to Aviatrix Controller using incognito mode, click on Sign in with SAML

Login as the user account created earlier with temporary password, and reset password

In the redirection screen, if you are fast enough, you can see Profile -> AWS_UsefulTools

Once logged in to controller, on top right side, it shows logged as RBAC User and belong to RBAC Groups: AWS_UsefulTools.

You may now validate that this account will only be able to use Useful Tools for the AWS access account you granted in permission group. Example, when tried to create a VPC in an Azure access account, will get access denied.
