Hello @Victor1989 ,
1. Azure Active Directory connector allows you to use a more granulated way of logs ingestion. For example, if you don't have ADFS in your environment you can simply disable it.
2. AAD Identity Protection connector allows to creation of alerts in Sentinel based on alerts that come from AAD IP.
I see that 1 ingests logs into two tables (AADUserRiskEvents and AADRiskyUsers), and 2 ingests logs into the (SecurityAlert) table. So with 2 you can only see alerts and with 1 you can see raw logs.
