You can use Google Cloud Directory Sync (GCDS) to automatically synchronize users, groups, and contacts so that the data in your Google Account matches the data in your LDAP server, such as Microsoft Active Directory.
Password Sync used to be known as G Suite Password Sync (GSPS).
You can use Password Sync to automatically synchronize your users' Google Workspace and Cloud Identity passwords with their Microsoft Active Directory passwords. When a user's Active Directory password is changed, Password Sync immediately pushes the change to their managed Google Account.
