Configuring Office365 SAML2 with MWARE IAM¶

This tutorial guides you through configuring SAML2 authentication for Office365 with MWARE IAM. Follow the instructions in the sections below to set this up.

The flow¶

The diagram below demonstrates the flow of how Microsoft Office365 uses MWARE IAM as a SAML2 federated authenticator to authenticate a user.

Prerequisites¶

• Office 365 Business Account with access to the Office 365 Admin Portal.

  Tip

  If you do not already have an account, you can use a 30-day trial version to try out this feature.

• Add a new domain to Office 365 using the Office 365 Admin Portal . For instructions on how to do this, see Add A Domain to Office 365 in the Microsoft documentation.

  Tip

  Office 365 SSO requires an internet-resolvable domain name to use as the suffix in each user’s username. You cannot federate the default domain that is provided by Microsoft that ends with "onmicrosoft.com".

  You can register a free domain using a site such as www.dot.tk if you do not already have a registered domain name.

• A Windows platform Windows Azure Active Directory Powershell installed. If you do not already have the Azure AD module, run the following commands to install the required modules.

  #uninstall any existing older version of the AzureAD module
  uninstall-module AzureAD
  
  
  install-module AzureAD
  install-module AzureADPreview
  install-module MSOnline

Configuring the MWARE IAM issuer¶

1. Navigate to <IS_HOME>/bin/ and run the following command to start MWARE IAM.

   • On Windows

   .\wso2server.bat

   • On Linux/Unix

   sh wso2server.sh

2. Access the following URL and log in to the management console: <https://localhost:9443/carbon/>

3. Click Resident Identity Provider under Identity Providers on the Main tab.

4. Expand the Inbound Authentication Configuration section and then expand SAML2 Web SSO Configuration.
5. Enter " wso2.microsoft" as the Identity Provider Entity Id value.
   

Configuring the claims¶

1. Click Add under Claims and then click Add Local Claim.
   Add the following local claims.

   Field	Sample value
   Dialect URI	http://wso2.org/claims
   Claim URI	http://wso2.org/claims/upn
   Display Name *	userPrincipalName
   Description	userPrincipalName
   Mapped Attribute (s) *	User Store Domain Name: PRIMARY Mapped Attribute: userPrincipalName
   Supported by Default	true

   Field	Sample value
   Dialect URI	http://wso2.org/claims
   Claim URI	http://wso2.org/claims/objectguid
   Display Name	ObjectGuid
   Description	ObjectGuid
   Mapped Attribute (s) *	User Store Domain Name: PRIMARY Mapped Attribute: objectGuid
   Supported by Default	true

Remove unsupported claims

The following attributes are not supported by Active Directory by default. Disable the following claims in MWARE IAM to avoid errors when updating the user profile.

To disable the claims, do the following.

1. Click List under Claims and select the http://wso2.org/claims dialect.
2. Click Edit next to the following claims and unselect the Supported by Default checkbox to disable the claim.
   • Country
   • Organization
   • IM

Configuring the service provider¶

1. Click Add under Service Providers and create a new service provider called 'Office365'.

2. Expand Inbound Authentication Configuration and then expand SAML2 Web SSO Configuration.
   Configure the following fields and leave the rest of the default configurations as it is.

   Field	Value
   Issuer	urn:federation:MicrosoftOnline
   Assertion Consumer URLs	https://login.microsoftonline.com/login.srf
   NameID format	urn:oasis:names:tc:SAML:2.0:nameid-format:persistent
   Enable Response Signing	Selected (True)
   Enable Signature Validation in Authentication Requests and Logout Request	Unselected (False)
   Enable Attribute Profile	Selected (True)
   Include Attributes in the Response Always	Selected (True)

3. Expand Claim Configuration and select Define Custom Claim Dialect.

4. Click Add Claim URI and add the following claims.

   Service Provider Claim	Local Claim	Requested Claim
   IDPEmail	http://wso2.org/claims/upn	Selected (True)
   NameID	http://wso2.org/claims/objectguid	Selected (True)

5. Set NameID as the Subject Claim URI and click Update to save changes.

Configure Azure AD to trust MWARE IAM¶

1. Log in to a Windows machine and start Windows Azure Active Directory Powershell.

2. Run the following command. It prompts for the Azure AD admin credentials.

   $cred=Get-Credential

   

3. Enter the credentials and click OK. Run the following command to connect to the service with the stored credentials.

   Connect-MsolService –Credential $cred

4. Run the following command to verify the availability of the validated domain.
   The ‘Status’ of the domain should be ‘Verified’, and ‘Authentication’ should be ‘Managed’.

   Get-MsolDomain

   

5. Configure the domain as a federated domain by providing the respective federation settings that match the MWARE IAM IdP. Store the federation settings in parameters.

   1. Store your domain.

      $dom = "wso2.cf"

   2. Set the IdP Logon URL for the POST SAML Authentication Request. For this tutorial, you can use the SAML SSO endpoint URL of WSO2 IS.

      $logonurl = "https://localhost:9443/samlsso"

   3. Set the issuer ID of the IdP. This value should be the Identity Provider Entity Id that you configured in the SAML configuration of the Resident IdP of WSO2 IS.

      $issueruri = "wso2is.microsoft"

   4. Set the IdP Logout URL for the POST SAML Logout Request. For this tutorial, you can use the SAML SSO endpoint URL of MWARE IAM.

      $logouturl = "https://localhost:9443/samlsso"

   5. Store the IdP certificate. Enter the Base64 encoded signing certificate of MWARE IAM.
      For the default key store configured in MWARE IAM, the certificate is as given below.

      Tip

      Note that the certificate value should be given in a single line without a break.

      How to obtain the PEM encoded certificate

      The PEM content of a certificate in a JKS file, can be obtained by following the steps below:

      1. Export the certificate from the keystone. The exported certificate will be in binary format.

      keytool -export -keystore <keystore-path> -alias <alias-of-the-certificate> -file <path-of-the-expected-certificate-file>
      
      e.g. keytool -export -keystore wso2carbon.jks -alias wso2carbon -file wso2carbon.crt

      1. Convert the above binary encoded certificate to a PEM encoded certificate.

      openssl x509 -inform der -in <path-of-binary-certificate> -out <path-of-expected-pem-content>
      
      e.g. openssl x509 -inform der -in wso2carbon.crt -out wso2carbon.pem

      1. Open the obtained PEM encoded certificate using a text editor and copy the certificate content excluding the BEGIN CERTIFICATE and END CERTIFICATE placeholders.

      $cert = "{certificate}"

      The certificate for the default key store configured in MWARE IAM is given below.

      Sample certificate

      $cert = "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"

6. Run the following command to establish trust.

   Set-MsolDomainAuthentication –DomainName $dom -Authentication Federated -PassiveLogOnUri $logonurl -SigningCertificate $cert -IssuerUri $issueruri -LogOffUri $logouturl -PreferredAuthenticationProtocol SAMLP

7. Run the following command to verify the federation settings.

   Get-MsolDomainFederationSettings -Domain $dom

   

You have now successfully set up trust between the on-premise identity provider of MWARE IAM and the Azure Active Directory.
