Updating WebSphere to support Azure AD OIDC authentication for Connections

Single sign-on is accomplished by setting up a trust relationship between the Connections server and Microsoft Azure using the WebSphere OpenID Connect Relying Party Trust Association Interceptor (OIDC Relying Party TAI). This requires that the WebSphereOIDCRP application is installed on each cluster.

Complete the steps in Adding an application in Azure AD for SSO with Connections, which results in values that you'll need in step 7 of the following procedure.

For every cluster, deploy WebSphereOIDCRP. In this example, the Connections applications are installed across the four clusters, AppsCluster, InfraCluster, PushCluster, and UtilCluster.

Note: The OIDC Replying Party TAI code is shipped as part of WebSphere Application Server. It is recommended that you are running WebSphere 8.5.5.18 which contains all required fixes. However, if you are running an earlier version of WebSphere, you must install at least version 1.3.0 of the OIDC jar. Find the latest version from https://www.ibm.com/support/pages/node/290565.
Apply a unique context root to each of the clusters. For example, for the Apps cluster, go to Enterprise Applications > WebSphereOIDCRP_AppsCluster.ear > Context Root For Web Modules.
Apply clusters to each module. For example, for the Apps cluster, go to Enterprise Applications > WebSphereOIDCRP_AppsCluster.ear > Manage Modules

Configure Global Security Custom Properties by clicking Security > Global security > Custom Properties and setting these properties to the following values:

Property	Value
com.ibm.websphere.security.disableGetTokenFromMBean Note: If this property doesn't exist, add it.	false
com.ibm.websphere.security.DeferTAItoSSO	com.ibm.ws.security.oidc.client.RelyingParty

As the WebSphere administrator, in the administrative console, click Security > Global security > Web and SIP security > Trust association.
Click Interceptors > New to add an interceptor.
For the interceptor class name, enter com.ibm.ws.security.oidc.client.RelyingParty.

Add the following properties and values.

Note: Use the values for {client_id}, {client_secret}, and {tenant} that you copied from steps 3 and 4 of the previous procedure.

Property	Value
provider_1.identifier	azuread
provider_1.clientId	{client_id} Find this value in Azure Connections application configuration

2. In the Realms section, click Add External Realm.
3. For the External realm name field, enter the value for {tenant}.
4. Click OK.
Create a new object cache instance with the JNDI name matching the one used in the last TAI property in the preceeding table (Resources > cache Instances > Object cache instances).
Go to Application servers > cluster > Container Services > Dynamic cache service, and for each cluster’s dynamic cache service make sure that cache replication is enabled and uses ConnectionsReplicationDomain.
Configure the trusted realm:
1. Click Security > Global security.
2. In the User account repository section, click Configure.
3. In the Related Items section, click Trusted authentication realms - inbound > Add External Realm.
4. In the External realm name field, enter the value for provider_1.issuerIdentifier from the Interceptor.
5. Click OK.
Add the root signing certificate of the Microsoft Certificate endpoint to the default trust store:
1. Click Security > SSL certificate and key management.
2. Click Key stores and certificates.
3. Select CellDefaultTrustStore and click Signer certificates.
4. Click Retrieve from port.
5. For the Host field, enter login.microsoftonline.com.
6. For the Port field, enter 443.
7. For the Alias field, enter cnxoidccert. (You will need to use this name as a value for property provider_1.signVerifyAlias. )
8. Click Retrieve signer information.
9. Click OK and save the changes.
Change security role for user/group for applications:
1. Click Applications > Application types > Enterprise Applications > Application name > Security role to user/group mapping.
2. For each resource, change the permission for all roles that have "All Authenticated in Application's Realm" to "All Authenticated in Trusted Realm."
Synchronize all nodes.
Restart the WebSphere server.

Return to step 8 of Adding an application in Azure AD for SSO with Connections and add a redirect URI.

Then Configure Connections to support Azure OIDC.
