What are the PAID and CAID in relation to a process?
The CAID (creator access ID) of a process is the user id of the user who initiated the creation of the process. Normally the PAID (process access ID) of a process is the same as its CAID except when the PROGID attribute is set for the program file of the process, in which case the PAID is set to the owner of the file and not the user id of the creator of the process.
