After some trial and error I have successfully got the Meraki Dashboard to authenticate admin logins against Azure AD. The below is the steps I used, hopefully they will be of use to others.

Creating the Azure Application

  • Sign into your Azure Portal and navigate to your Azure Active Directory tenant.
  • On the left select Enterprise applications and select New Application
  • Select Non-gallery application
  • Give the application a display name such as Meraki Dashboard and click Add
  • Within your new application navigate to Manage => Single sign-on and select SAML as the sign-on method

Meraki SSO Configuration

  • We will need two bits of information to configure the Meraki side. Still on the Manage => Single sign-on section on the Azure AD application;
  • Take a copy of the Thumbprint under the SAML Signing Certificate section.
  • Take a copy of the Logout URL under the Set up Meraki Dashboard section
  • Login to you Meraki dashboard and navigation to Organisation => Configuration => Settings
  • Under SAML Configuration section set the SAML SSO drop down to SAML SSO Enabled
  • Paste the previous Azure thumbprint into the fingerprint field and add colons to separate it into a hex sting. i.e if it was B5F3A2 it would change to B5:F3:A2
  • Paste the previous Azure logout url into the “SLO logout URL” field
  • Click Save
  • After clicking save your “Consumer URL” will be visible. Take a copy of it, we will need it in a second.

Completing Azure application’s Basic SAML Configuration section

  • Click the pen icon to edit the “Basic SAML Configuration” section.
    • Identifier (Entity ID): https://dashboard.meraki.com
    • Reply URL: Your “Consumer URL” from the previous section
  • Click Save

Creating a Meraki Role

  • Back on the Meraki portal navigate to Organisation => Configuration => Administrators
  • Click Add SAML role
  • Pick a name – We will need this later
  • Assign the desired permissions and save the configuration.

Completing Azure application’s attributes and claims section

  • Back within the Signal Sign-on section of our Enterprise application we need to complete the “User Attributes & Claims” section. Click the pen icon to edit the setup.
  • Delete all the current rows, there will be one you can’t delete but don’t worry about that.
  • Click Add new claim
    • Name: username
    • Namespace: https://dashboard.meraki.com/saml/attributes
    • Source: Attribute
    • Source Attribute: user.mail
    • Click Save
  • Click Add a new claim
    • Name: role
    • Namespace: https://dashboard.meraki.com/saml/attributes
    • Source: Attribute
    • Source Attribute: The name of the role you created on the Meraki portal
    • Note: I had some issues putting free text into the source attribute field at first. Typing the name and then pressing the TAB key seemed to work for me.
    • Click Save
  • Still within the attributes and claims section click the pen icon to the right of “Name identifier value:” at the top and change the Source Attribute to user.mail

Giving access to use the application

  • Within the application navigate to the Manage => Users & groups section
  • Click the Add user and add the required administrator, maybe just start with yourself.

Testing

  • Back within the Manage => Single Sigon-on section press the Test button at the very bottom.
  • Press the Sign in as current user button.

Troubleshooting

Notes

  • If the user signing in already has a Meraki admin account the signin will fail. You will need to delete the Meraki admin account first.
  • The Meraki dashboard doesn’t currently support
    Identity Provider (IdP) initiated sign-in. You will not be able to sign in directly from the Mearki dashboard, you will need to sign-in via https://myapps.microsoft.com/ or your Office 365 portal or you can find a direct URL for the app on the Manage => Properties section on the Azure application in the “User access URL” field.
