4.1 Publishing an Autodiscover Server Location

The following topology is used in this example:

  • The DNS name of the mail server is Mail.Contoso.com.

  • The DNS name of the Web service computer is WebService.Contoso.com. It has a valid SSL certificate.

  • Autodiscover Web services are available at:  https://WebService.Contoso.com/Autodiscover/Autodiscover.xml.

  • The mailbox server and Web services server are configured to use MailLdap.Contoso.com as their LDAP server.

  • Clients are configured to use ClientLdap.Contoso.com.

The following figure illustrates this topology.

An administrator wants to publish Autodiscover services for mailboxes on Mail.Contoso.com. For various reasons, the administrator is unable to configure "https://Contoso.com/Autodiscover.Autodiscover.xml" to respond to Autodiscover requests. Instead, the administrator uses [RFC1034] and [RFC4210] to create SSL certificates that allow the Autodiscover server to HTTP 302 redirect "https://Autodiscover.Contoso.com/Autodiscover/Autodiscover.xml" to "https://WebService.Contoso.com/Autodiscover/Autodiscover.xml".

Also, the administrator creates and publishes two LDAP objects to help clients find the Autodiscover server.

For MailLdap.Contoso.com, the administrator publishes the following:

 DN: CN=WebServices,CN=Autodiscover,CN=Protocols,CN=WebServices,CN=Servers,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=Contoso,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=Contoso,DC=com
 Changetype: add
 Objectcategory: serviceConnectionPoint
 serviceBindingInformation: https://WebService.Contoso.com/Autodiscover/Autodiscover.xml
 Keywords: "77378F46-2C66-4aa9-A6A6-3E7A48B19596"

On the client LDAP server, the administrator publishes the following:

  
 DN: CN=mail.contoso.com,CN=Microsoft Exchange Autodiscover,CN=Services,CN=Configuration,DC=Users,DC=Contoso,DC=com
 Changetype: add
 Objectcategory: serviceConnectionPoint
 serviceBindingInformation: LDAP://MailLdap.Contoso.com
 Keywords: "67661D7F-8FC4-4fa7-BFAC-E1D7794C1F68"
