i added support saml 2.0 sso okta application using kentor authservices .net package , first action done user clicking "login okta" button , being redirected okta's sign in page saml request token generated kentor.
in scenarios user email (username in okta) known beforehand , want pre-populate username textbox on okta's sign in page value.
is possible that, example providing desired username in saml request or in cookies?
the saml standard has support including subject (that user name in saml lingo) in authnrequest. unfortunately kentor.authservices doesn't support (yet). there has been work done (see https://github.com/kentorit/authservices/issues/430) don't know current status.
then of course need check whether okta supports reading data.
