Power BI with LDAP Authentication?

Synchronizing users’ identities between local and cloud directories is a great way to let users access different resources on both on-premises and cloud environments with just a single set of credentials. 

For reference: How to sync on-premises Active Directory to Azure Active Directory with Azure AD Connect?

Power BI Embed has two versions: user owns data / app owns data.

From your statement, I think you use user owns data. You need to sign in with accounts which has access to the report.
