Kerberos keytab to service authorization of all AD users

  active-directory, kerberos, keytab, windows

Say I have keytab file generated for a service to someUserAccount. Also I have an SPN registered to someUserAccount. I want to authorize to the service i.e. get ticket from KDC for any user of AD only with username and without password. Is that possible in my scenario or at all using Kerberos?
