I have a user that needs to access two Confluence instances. TenantA uses Atlassian Access and SSO with AzureAD. TenantB uses normal confluence user accounts.
This user has a UPN that matches user@TenantB.com but has an email alias for user@tenantA.com.
User@tenantB.com is used to log in to TenantB as expected. Is it possible to use this email/UPN to log in to TenantA as well?
Is it possible to solve this problem without changing the UPN for the user?
(Using user@tenantA.com to log in to TenantA doesn't work since the user doesn't have this address as UPN)
