 Hi,
Note that packet-kerberos-template.c isn't used to generate

Yes, I've just discovered that. And indeed, changing the value in
packet-kerberos.c seems to solve the issue.

extensions are wrong?

It appears like MS extensions for Kerberos pre-auth type constants, such
as:
#define KRB5_PA_PAC_REQUEST         -128  /* = 0xFFFFFF80 =
(gint32)((gint8)0x80) MS extension */

are wrong - should be 128 (which is 0x80 btw), for example, based on a
capture I've done and on
http://download.microsoft.com/download/a/e/6/ae6e4142-aa58-45c6-8dcf-a657e5900cd3/%5BMS-KILE%5D.pdf(see section 
3.1.5.1)
Is it OK to fix them in packet-kerberos-template.c? Anyone knows where the
mistake comes from?

TIA,
Y.
