How to set SessionNotOnOrAfter attribute in Entra ID?

Question

Jestin Ma 20

GitHub supports the SessionNotOnOrAfter attribute in the AuthnStatement element.

However, I do not see that attribute in the SAML docs for Entra.

Can anyone confirm whether it is possible to set this attribute from Entra ID?

Entra ID does not support SessionNotOnOrAfter attribute and does not allow configuration of session lifetimes derived from the SAML Response.

Github uses the SAML SessionNotOnOrAfter value on the SAML Assertion to define the relying application's session length (See Page 27 of the SAML spec: http://docs.oasis-open.org/security/saml/v2.0/saml-core-2.0-os.pdf_

A potential solution would be to configure conditional access policies with session frequency.

Have you looked at the refreshTokensValidFromDateTime attribute? Here's the corresponding Graph method: https://learn.microsoft.com/en-us/graph/api/user-invalidateallrefreshtokens?view=graph-rest-beta&tabs=http

I believe that is a separate attribute which controls SAML token lifetime. SessionNotOnOrAfter controls the session duration/timeout on the application side (after which the user will be required to re-authenticate and may or may not hit the SAML token lifetime).
