IDCS integration with Azure AD for O365 SSO
SummaryWe want to integrate IDCS with Azure AD to provide SSO for O365 products
Our IDCS's identities are synchronized from on-premise OID, so the user ID is a numeric string for login, e.g. 1234567, instead of email address. We will setup IDCS as IDP, Azure O365 as SP in the federation. My first question is: will the numeric user ID instead of email address work for this SSO login in the federation?
If the numeric ID works, according to the IDCS/Azure federation integration instruction, on IDCS side, Name ID Format and Name ID Value need to be configured; on Azure side, Incoming Claim Type / Incoming Name ID Format need to be configured. What are the possible values to configure these fields in both IDCS and Azure sides?
