Before you can use the Mobile SSO for iOS authentication method, you must initialize the Key Distribution Center (KDC) in the Workspace ONE Access appliance.
To initialize KDC, you assign your Workspace ONE Access hostname to the Kerberos realms. The realm name is entered in upper-case letters. If you configure subdomains, type the subdomain name in lower-case letters.
Prerequisites
Workspace ONE Access is installed and configured.
Realm name identified. See Using the Built-in KDC for Workspace ONE Access.
Procedure
What to do next
Create public DNS entries. DNS records must be provisioned to allow the clients to find the KDC. See Creating Public DNS Entries for KDC with Built-in Kerberos.
