Problem with SSO / SAML Setup with Azure AD

[Minh Tran]

After completing all the documented steps and deleting and retrying the app configuration in Azure a few times, we still get this error when trying to configure SSO: 

Browser error we get after clicking login and getting redirected from the login window:

This sts.windows.net page can't be foundNo webpage was found for the web address: https://sts.windows.net/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxxx?SAMLRequest=buaZHXoirzCQAsIdFm3ZLveZOnjKkuE1UOvZRlNWM1Ex0rKtlkkE8yxFFtLAawoSV5mjOaVjRt9lnFWclZExfl7BuJtpeEPkxOzslfi1O8iJB%2F3O%2B3dPtltyfR19cGJwG59MXPdP%2B%2BqOuL4bUdsrjSxWlR8j%2BJz5P3Nt6O6PPE3ay3zmj5O1oZ4443XkFQLQl%2BVCS6dX6A8G%2BnWZydX3RH%2B7OUqwG0WXWdV4gkWVy4f5%2Fr4g8%3D&RelayState=4b117eed-5515-4880-9131-32c2f36b7a91
HTTP ERROR 404

Any insights into the connection error?

Clearly I am a novice at this. Thanks for the assist @Hector Menchaca . Just raced through the instructions and did not follow them closely enough. Assumed the order they provided was the order to enter them in the SAML set up.

Hello @Minh Tran ,

Welcome to Atlassian Community!

In order to solve this issue you just need to swap the values Identity Provider Entity ID and Identity Provider SSO URL in your SAML configuration.

Regards,

Thanks!

Thanks for your reply - This is for Atlassian Cloud and we have followed the instructions in both those links you provided (although we are not setting up provisioning just yet, just SSO). We've repeated the steps multiple times and deleted the app and restarted without success. After double and triple checking that we copied the contents to and from Azure AD and Atlassian SAML set up correctly, we continue to run into the 404 error.

Hi @Minh Tran 

It appears there may be a configuration issue, likely related to the ACS URL configuration.

To resolve this, you'll need to collect the SAML metadata from both the Atlassian Access and Azure AD and configure them accordingly.

For detailed guidance on the setup, you can refer to the following document:

https://support.atlassian.com/provisioning-users/docs/connect-to-azure-active-directory/

https://learn.microsoft.com/en-us/entra/identity/saas-apps/atlassian-cloud-tutorial

As an SSO vendor, we have created an extensive setup guide for configuring SAML SSO with Azure AD for our Data Center app. You can refer to its Azure AD configuration as well.
