JamesC.99903 (Customer) asked a question.
I'm integrating an app that has a userID that can not be constructed based on OKTA profile data. I added an attribute to the base profile with the expectation that the user could edit their profile data and that info would be passed. BUT Okta is telling me that the attribute must be read-only.
How do I create and read/write attribute that can be passed as the SAML Subject?
Thanks,

Hi James,
I have not explored this option but I think you can try writing a SAML hook wherein you can pass the custom attribute as a SAML subject in the Assertion. try exploring this, may be this will help.
