To enable Kerberos authentication, you must configure two service principal names (SPNs).
An SPN is a unique identifier of a service instance. SPNs are used by Kerberos to associate a service with a domain.
setspnto configure two SPNs for each PingOne region. To find the SPNs for various PingOne regions, see SPN reference.
You can also use ADSI Edit to configure the SPN values.
The purpose of two SPNs is future proofing. Ping Identity will migrate its
infrastructure in the coming months. Adding the second
HTTP/kerberos.pingone.com SPN ensures that your configuration
will continue to work after the migration.
- On the domain controller, open a command prompt as an administrator.
Enter the following command
setspn -S HTTP/<regionalPingOneaddress> <sAMAccountName>where
<regionalPingOneaddress>is the SPN you want to add and
<sAMAccountName>is the service account name that you want to update.Note:
When you run the
setspncommand, you must capitalize
HTTPand follow it with a forward slash (
setspn -S HTTP/d3vol3lyj0eg62.cloudfront.net ping-one-kerberos-svc-account
To find the SPNs for various PingOne regions, see SPN reference.
