I have defined multiple AssertionConsumerService and set up the IDP to look for this custom XML file, which works for the one URL that is defined in the Single Sign On URL. I wanted different service providers (based on subdomains) to all point to one IdP.
For my case, I have dev and qa in separate instances, but would like them each to authenticate to the same Okta preview sandbox. Is there a reasonable solution to this with Okta?
Thanks for posting your inquiries in Okta Community.
You can integrate and provisioned multiple SPs or instances on Okta thru SWA, SAML, WS-Federation and customed templates. You may refer on this link: http://developer.okta.com/docs/guides/oan_guidance.html for more detailed information.
Please let me know if you need any additional information or call Okta Support for more information. Thank you.
