Thanks for posting your question in the Microsoft Q&A forum!
To find the Sign on URL field in the Basic SAML Configuration section of your Microsoft Entra SAML Toolkit, you will need to contact the service provider (SP) that you are configuring SSO with.
The Sign on URL is typically provided by the Service Provider and is specific to the application that you are integrating with. please refer to the documentation of the service provider to get the Sign on URL
Once you have obtained the Sign on URL from the Service Provider, you can include it in your XML file for importing into your Microsoft Entra SAML Toolkit.
Hope this helps. Do let us know if you any further queries.
Thanks,
Akhilesh.
