The short answer is yes. Active Directory uses Kerberos for
authentication, which PostgreSQL supports through the GSS authentication
mechanism.

LDAP authentication is also supported but is strongly discouraged in an
Active Directory environment (by Microsoft) as Kerberos should be used
instead since it's a much more secure solution. LDAP-based
authentication requires sending the password to PG as cleartext.

Thanks!
