VPN access
VPN (virtual private network) provides secure access over the Internet to private networks, such
as the network at your company or school. Use Network settings on iPhone to congure and
turn on VPN. Ask your administrator what settings you should use.
VPN can also be set up automatically by a conguration prole. When VPN is set up by a
conguration prole, iPhone may turn VPN on automatically whenever it’s needed. For more
information, contact your administrator.
LDAP and CardDAV accounts
When you set up an LDAP account, you can view and search for contacts on your organization’s
LDAP server. The server appears as a new group in Contacts. Because LDAP contacts aren’t
downloaded to iPhone, you must have an Internet connection to view them. Check with your
administrator for account settings and other requirements (such as VPN).
When you set up a CardDAV account, your account contacts are synced with iPhone over the air.
You may also be able to search for contacts on your organization’s CardDAV server.
Set up an LDAP or CardDAV account: Go to Settings > Mail, Contacts, Calendars, then tap Add
Account. Tap Other. Ask your service provider or administrator what settings you should use.
