It seems that the extraction of SIDs from a PAC is doable with
the libraries. I can get the SIDs by calling these functions:
The SIDs from user_info->sids can be translated to uid/gids with
wbcSidsToUnixIds. Is this an acceptable use of Samba libraries by
an external application? My biggest fear is that those functions
are considered internal to Samba and external applications would
break when they are changed.
