Hi @javad,
I have done some more digging and found this: Session timeout in Kibana SAML · Issue #159 · opensearch-project/security-dashboards-plugin · GitHub
(NOTE: this didn’t make it into the 2.12.0 release, and instead will be available in 2.13.)
this is related to the fix: Fix cookie expiry issues from IDP/JWT auth methods, disables keepalive for JWT/IDP by derek-ho · Pull Request #1773 · opensearch-project/security-dashboards-plugin · GitHub
Please have a look and let me know if you have any further questions.
Best,
mj
