Grafana provides many ways to authenticate users. Some authentication integrations also enable syncing user permissions and org memberships.
Here is a table showing all supported authentication providers and the features available for them. [Team sync]({{< relref "../enterprise/team-sync.md" >}}) and [active sync]({{< relref "../enterprise/enhanced_ldap.md#active-ldap-synchronization" >}}) are only available in Grafana Enterprise.
