9bd2680485 heimdal:kdc: Do not generate extra PAC buffers for S4U2Self service ticket 
Normally samba_wdc_get_pac() is used to generate the PAC for a TGT, but
when generating a service ticket for S4U2Self, we want to avoid adding
the additional PAC_ATTRIBUTES_INFO and PAC_REQUESTER_SID buffers.

1f4f3018c5 heimdal:kdc: Always generate a PAC for S4U2Self 
If we decided not to put a PAC into the ticket, mspac would be NULL
here, and the resulting ticket would not contain a PAC. This could
happen if there was a request to omit the PAC or the service did not
require authorization data. Ensure that we always generate a PAC.

4b60e95164 kdc: Remove PAC_TYPE_ATTRIBUTES_INFO from RODC-issued tickets 
Windows ignores PAC_TYPE_ATTRIBUTES_INFO and always issues a PAC when
presented with an RODC-issued TGT. By removing this PAC buffer from
RODC-issued tickets, we ensure that an RODC-issued ticket will still
result in a PAC if it is first renewed or validated by the main DC.
