Unable to authenticate user after federating new domain

Laxman Oza 1

I have hybrid environment setup and federated identities are working as expected. We already have multiple domain added in the Azure and federated as well. I have added one more domain(e.g ABC.COM) in Azure and federated the same using the PowerShell command using multiple domain switch.

when i try to authenticate the user with newly added domain (user1@jaswant .com). If fails with error "The requested federation realm object 'urn: com' does not exist"

@Andy David - MVP : Can you please me on this ?

Hi @Laxman Oza · Thank you for reaching out.

Is it 'urn: com' in the error or there is a specific url like 'http:// hostname/adfs/services/trust'?

Do you have child of this domain (child.abc.com) already federated?

Is WIA (Windows Integrated Authentication) being used when users are trying to access the application?

Issue was fixed by updating the this rule- Issue issuerid when it is not a computer account (added the newly federated domain in this rule)

Followed this thread- https://community.spiceworks.com/topic/2088405-requested-federation-realm-object-user-extra-co-uk-does-not-exist

The child domain for abc.com was not federated

our O365 using WIA

Thanks for your help
