Azure AD Connect accounts
Azure AD Connect uses the following 3 accounts to synchronize data between Active Directory (on-premises) and Azure Active Directory (cloud):
- AD DS Connector account: Read/write information to Windows Server Active Directory
- ADSync Service account: Run the synchronization service and access the SQL database
- Azure AD Connector account: Write information to Azure AD
Let’s find all 3 Azure AD service accounts and note them down.
AD DS Connector account
The AD DS Connector account, which reads/writes information to Windows Server Active Directory, can be in these two places.
Start Synchronization Service Manager on the Azure AD Connect Server. Click on Connectors > internal domain > Properties.
In our example, it’s the internal domain with the name exoip.local.
Click Connect to Active Directory Forest. The user name shows the AD DS Connector account.
