EXSSLVPN: Error "ActiveSync Access requires the use of a Realm that uses a single Active Directory authentication Server, but no such Realms are configured" While trying to configure an Activesync URL Resource.
When no Active Directory authentication server is configured, Aventail returns the following error in the resource page under ActiveSync feature integration:
"ActiveSync Access requires the use of a Realm that uses a single Active Directory authentication Server, but no such Realms are configured".
NOTE: ActiveSync integration is supported only with Active Directory authentication server. LDAP authentication server or even Chained Authentication is not supported for ActiveSync Resources.
Steps for Resolution:
Step 1: Go to Authentication Servers page within Aventail Management Console Step 2: Add new authentication server (Select Active Directory) Step 3: Configure it as per your Active Directory Environment. Refer Administrator Guide for more details. Step 4: Navigate to Resource Section and Modify the Exchange URL Resource intended for ActiveSync Setup Step 5: Extend ActiveSync section and then configure it as per requirements. Step 6: Note that the previously displayed Realm/Authentication Server error is no longer displayed.
