Okta is pretty new to our organization and every integration we have done has been standard mappings from AD. Talking to our admin we haven’t had to pass anything as a SAML attribute to a third party that wasn’t in AD. We now have a requirement from another party to do that exact thing. My experience with Okta is next to none, so I’m not sure on where to start for searching or documentation. If someone could help point me in the right direction or if you need more information to help diagnose the issue I will give you what I can.
Let me update this to try and give more context if anyone has any ideas. Below I included a screenshot from the document the vendor gave us. This serviceParameters SAML attribute is a unique value to each entity a user may be viewing on an internal system at the time. We would need to take a data point from that entity and put it into a SAML assertion as the VendorUID you see in the fourth column. One idea our networking admin had was using relay state to accomplish this. I’m not sure how to do this since I have no experience with Okta at the moment.
