IS IT POSSIBLE TO LOGIN WITH CACHED CREDENTIALS WHEN USING A KERBEROS LOGIN?
No. You will be able to log into the machine with the cached credentials. However, your will not have a Kerberos ticket. This means you will not be authorized to use any resources. To see a list of tickets that you have when you log in with your Kerberos account, use the KLIST.EXE utility with the command klist.exe tickets.
