SAML response has eppn value (alexng@sysdev.pclan.xxx), but shibd still not working, anyone knows how to fix this issue? thanks
We might need to wait until our Shib hero @Don Sizemore is around. Timezones... :wink:
Also, I am moving this thread to #troubleshooting as it does not seem to be dev related (for now)
This topic was moved here from #dev > SAML Login issue by Oliver Bertuch.

@alexng what's powering the IDP?
I suppose they might already be back to sleep... https://www.timeanddate.com/worldclock/macau/macau
Are they missing config bits for the scope? https://shibboleth.atlassian.net/wiki/spaces/IDP30/pages/2496987397/ScopeConfiguration
I usually ask to try the equivalent of https://demo.dataverse.org/Shibboleth.sso/Session
I got message form "/Shibboleth.sso/Session" , other attributes received successfully

You mean need to add the scope in attribute-map.xml ?
my attribute mapping is using this one https://guides.dataverse.org/en/latest/_downloads/2fa33ab92f96836906cbf6d9d3badeb9/attribute-map.xml
thank you all of you, I solved the problem, I change the "eppn" scope in attribute-policy.xml
Glad you could figure it out!
