Configure and test Microsoft Entra SSO for Citrix Cloud SAML SSO

Configure and test Microsoft Entra SSO with Citrix Cloud SAML SSO using a test user called B.Simon. For SSO to work, you need to establish a link relationship between a Microsoft Entra user and the related user in Citrix Cloud SAML SSO. This user must also exist in your Active Directory that is synced with Microsoft Entra Connect to your Microsoft Entra subscription.

To configure and test Microsoft Entra SSO with Citrix Cloud SAML SSO, perform the following steps:

Configure Microsoft Entra SSO - to enable your users to use this feature.
1. Create a Microsoft Entra test user - to test Microsoft Entra single sign-on with B.Simon.
2. Assign the Microsoft Entra test user - to enable B.Simon to use Microsoft Entra single sign-on.
Configure Citrix Cloud SAML SSO - to configure the single sign-on settings on application side.
Test SSO - to verify whether the configuration works.

Citrix Cloud SAML SSO application expects the SAML assertions in a specific format, which requires you to add custom attribute mappings to your SAML token attributes configuration. The following screenshot shows the list of default attributes.

In addition to above, Citrix Cloud SAML SSO application expects few more attributes to be passed back in SAML response which are shown below. These attributes are also pre-populated but you can review them as per your requirements. The values passed in the SAML response should map to the Active Directory attributes of the user.

Name	Source Attribute
cip_sid	user.onpremisesecurityidentifier
cip_upn	user.userprincipalname
cip_oid	ObjectGUID (Extension Attribute)
cip_email	user.mail
displayName	user.displayname

Note

ObjectGUID must be configured manually according to your requirements.

On the Set up single sign-on with SAML page, in the SAML Signing Certificate section, find Certificate (PEM) and select Download to download the certificate and save it on your computer.
On the Set up Citrix Cloud SAML SSO section, copy the appropriate URL(s) based on your requirement.
