What logs exist in the backend? For us, 7.5.6 is working with SAML2 :)

Could you also provide the log of Artemis? Is there anything in particular regarding SAML ?

dfuchss commented 3 weeks ago

Especially, the error user does not exist in backend is interesting because the user will be created during first login. Maybe connecting a debugger to the instance and adding a breakpoint to the Saml2Service provides rhe needed insights .

hi @dfuchss I am fixed by work around to update code. becase I am using SAML authentication with Microsoft Entra ID with have EntityID difrreent in asserting and RelyingParty

I think we need have to config option in application-saml2 file like entityId-asserting-detail
