The first step in configuring an application to support SAML based Single Sign-On from Okta is to set up an application in Okta.
In SAML terminology, what you will be doing here is configuring Okta (your SAML Identity Provider or "SAML IdP"), with the details of your application (the new SAML Service Provider or "SAML SP").
Here is how to set up a SAML application in Okta:
Important: If you are using the Developer Console you will first need to switch to the Classic UI.
If you see Developer Console in the top left, click it and select Classic UI to switch.
Log in to your Okta organization as a user with administrative privileges. If you don't have an Okta organization, you can create a free Okta Developer Edition organization.
Click on the Applications link in the upper navigation bar
Click on the green Create New App button
In the dialog that opens, select the "SAML 2.0" option, then click the green "Create" button. If you do not see this option, make sure you are in the Classic UI (see Note above).
In Step 1 "General Settings", enter "Example SAML Application" in the "App name" field, then click the green Next button.
In Step 2 "Configure SAML," section A "SAML Settings", paste the URL below into the "Single sign on URL" and "Audience URI (SP Entity ID)" fields:
In the "Attribute Statements" section, add three attribute statements:
In Step 3 "Feedback", select "I'm an Okta customer adding an internal app", and "This is an internal app that we have created," then click Finish.
The "Sign On" section of your newly created "Example SAML Application" application appears. Keep this page open it a separate tab or browser window. You will return to this page later in this guide and copy the "Identity Provider metadata" link. (To copy that link, right-click on the Identity Provider metadata link and select Copy)
Right-click on the Assignments section of the "Example SAML Application" application and select Open Link In New Tab (so that you can come back to the "Sign On" section later).
In the new tab that opens, click on the Assign button and select Assign to People
A dialog titled "Assign Example SAML Application to People" will open. Type your username into the search box, select the Assign button next to your username.
Verify the user-specific attributes, then select Save and Go Back.
Click "Done" to exit the assignment wizard.
You are now ready to configure SAML in your application. The information in the tab you opened in step 10 contains the information that you'll need to configure SAML in your application.
