KRB_AP_REQ data buffer length

[Srinivas Cheruku]

Hi,

I will get a data buffer containing DER encoded KRB_AP_REQ from a client
application. This client application is built using the raw MIT libraries
and not GSS. Will the first few bytes of the encoded data buffer hold the
size of the KRB_AP_REQ? 

Thanks and Regards,
Srini

The implementation guarantees it will be less than your total address
space;-)

It contains a ticket; the spec sets no length on tickets.  Typically
with MIT Kerberos, you can see messages containing ap_req as short as
511 bytes, but messages exceeding 4KB are not unheard of.  You
probably should support at least 64k, probably significantly more.
