In the Microsoft Azure Portal go to Azure Active Directory and select the Enterprise Applications blade.
Select New Application, and then Create your own application, choose the ‘Integrate any other application you don’t find in the gallery (Non-gallery)' choice, enter ‘Re-Leased’ as the name, and click Create.
Select the Single sign-on blade and choose the SAML option.
Under step 1 (Basic SAML Configuration) click the Edit option. And provide the information from the Manage Single Sign On page within the Re-Leased application Settings (pictured below).
The Re-Leased field Audience URI (Service Provider Entity ID) goes into the Azure Identifier (Entity ID) field.
The Re-leased field ACS URL goes into the Azure Reply URL (Assertion Consumer Service URL) field.
The Re-Leased field Sign-on URL goes into the Azure Sign on URL (Optional) field.
Leave the other fields empty, click Save and then close the Basic SAML Configuration blade.
Scroll down the page to step 3 (SAML Certificates).
Download the Certificate (Base 64) and save the .cer file. Open this file with a text editor such as Notepad. Copy and paste the entire contents (including the BEGIN/END CERTIFICATE text) into the Re-Leased Public Key field.
Scroll down to step 4 (Set up Re-Leased). Copy the Azure Login URL field into the Re-Leased Sign-on Url field. Then Save.
The configuration is now complete. Within Azure you can now assign users or groups to this enterprise application to allow them to sign in.
