Differentiate the ServiceTicket issued from Kinit vs PKinit

[Jim Shi]

Hi, Ken,
 The TGS ticket flag is set on KDC server.  When the client get TGS back from the server, he/she is able to see the flag set by the KDC. Looks klist commands will show flags.

However if the client passes the ticket to some service for verification, , the service will not be able  see the these flags. Is that right? My understanding is that  these flags are not  passed to service??



Thanks
Jim
