What ports does Adaxes use?

For a simple network architecture (one managed Active Directory domain, with all Adaxes components installed on the same computer), open the following TCP and UDP outbound ports on the computer running the Adaxes service, and the same inbound ports on your domain controllers:

  • 389 LDAP
  • 636 LDAP (SSL)
  • 3268 LDAP (Global Catalog)
  • 3269 LDAP (Global Catalog, SSL)
  • 88 Kerberos
  • 135 RPC Endpoint Mapper
  • Full dynamic RPC port range

For anything beyond that, like opening ports to on-premises Exchange servers, configuring Adaxes to use specific domain controllers, restricting the dynamic RPC range, and general best practices, see Adaxes network usage.
