Atlassian Access issues / Authentication Policy missmatch ?/ SSO issue

[felix.weber]

Hi all,

maybe you can help me:

I have migrated 2 Organisation:

• Orga A and Orga B
• Orga A has Atlassian in place.
• Login to atlassian is done via SSO.

I want to connect users from Orga B to Atlassian Access as well.

I have successfully verified the B-Domain and claimed their users.

• SSO login to Orga A works
• SSO login to Orga B does not work
  

However when trying to access the Orga-B via Atlassian-SSO the login does not work:

https://id.atlassian.com/login/callback?error=unauthorized&error_description=authentication-policy-strategy-mismatch%3FcurrentConnection%xxxxxxxxx%26policyConnection%3Dnull&state=https%3A%2F%2Fstart.atlassian.com%2F

Due to the URL Error I thought this might be related to "recently" released feature "Authentication policies" atlassian released end of last year (https://support.atlassian.com/security-and-access-policies/docs/understand-authentication-policies/)
Keep in mind OrgaA has been created before October2020 and OrgaB just recently

In general the SAML connection between our IDP and Atlassian works: 

When updating e.g. the Email addr in the IDP for a user in OrgaB the Email addr will indeed be updated in the user management. 

thanks in advance for your help

Hello Dblake,

Welcome to Atlassian Community!

Searching on our tools here, I wasn't able to find any site where you are a user.

I also searched using the domain of your email and found other people, but none of them were users on a site as well.

With that said, I can't see what happened to your account and also who are the admins.

As here is a public space, it is up to you if you want to share what is the URL that you used to log in, but even though, for private reasons, I can't post here the full names of the admins.

Another option is to create a ticket with our support that it's private, so you can share all the necessary information. You can create a ticket on support.atlassian.com.

Regards,
Angélica
