Hi All,
I have two apps (APP-A and APP-B) . Both App are registered in OKTA .
- APP-A is created using OIDC i.e on login to APP-A we receive access token and id token.
- APP-B is created using SAML i.e on login we receive session cookies , that get stored in browser.
Question is : How to establish seamless login from APP-A (OIDC) to APP-B (SAML) . i.e conversion of access token to session cookies OR OIDC to SAML .
Please provide detailed inputs.
Please provide okta documentation for reference.
In 2019 same question was unanswered . https://support.okta.com/help/s/question/0D51Y00006iRLym/oidc-to-saml-sp?language=en_US
Please provide the resolution .
Note : Already I have implemented seamless login from SAML to OIDC.

Hi Rajesh,
This is Gabriel. Thanks for posting on our community!
As my colleague mentioned on the article you referenced, unfortunately there is no direct answer to your query. Due to the highly complex nature of the workflow you described and the numerous variables at play there is no "one-size-fits-all" solution. Such a use case has be to be analyzed from all perspectives before a custom solution can be developed. As such, we do not have any documentation on this that I can share.
Please submit a support ticket with us so we can have a detailed discussion on this. This will help us determine if and how we can tackle this.
Hope this will be useful for everyone :
Please use below session cokkie redirect url to seamless authenticate SAML app from OIDC app.
https://{{ okta domain}}/login/sessionCookieRedirect?token={{SessionToken or id_token or access-token }}&redirectUrl=/home/client_/0owert6f26sWQRTYg1/wtlrueophfge6ewrLJTYE
redirect url --> login to saml app and copy embedded link.
