This configuration parameter specifies additional service principals for entries in the Kerberos key table. The key table is populated by default with the service principals host and ftp cifs.
This parameter’s value must be one or more principal service names, separated by a space or by a comma. For example:
adclient.krb5.service.principals: ldap nfs
If this parameter is not defined in the configuration file, no additional principal names are added to the Kerberos key table.
