Can I configure/use SSO with UPN

Occasional Contributor


We have an on premise AD that syncs to Azure AD using AD connect .. it is set to use pass-through authentication .. the name of the domain differs from the domain used to identify users - UPN .. 


So lets say the domain is ad.local and users use upn to authenticate 


So my question is:

Can we still manage to have SSO works both for web apps and Microsoft Teams desktop


Thanks in advance

Hi, if you are referring to Seamless single-sign on as per  -, then you should have no issues setting this up.  If you are already syncing from local AD with PTA, and the UPN's in O365 are correct, then you will have no issues.

@PeterRising  yep .. you are absolutely right .. worked like a charm
