credentials cache type KRB5_FCC_FVNO_4

[Srinivas Cheruku]

Hi,

 

>From code I found that, when a TGT is fetched from KDC, the cache header
stores times_offset based on the authtime of the ticket. Looks like you can
also store usec_offset in the cache header. But I haven't seen any code
setting the same.

 

Can anyone help me to understand 

1.       Why this header is needed ?

2.       When the values times_offset and usec_offset are set?

3.       When the values set in header are used?

 

Thanks,
Srini
