"JobPrivateAccess all" does not work

[miztake]

According to man 5 cupsd.conf, "all" can be specified for JobPrivateAccess.

---

DIRECTIVES VALID WITHIN POLICY SECTIONS
The following directives may be placed inside Policy sections in the cupsd.conf file:

   JobPrivateAccess all

   JobPrivateAccess default

   JobPrivateAccess {user|@group|@ACL|@OWNER|@SYSTEM} ...

---

Even if "JobPrivateAccess all" is set, the result of lpstat is unknown.

~]# lpstat -o
devnull01-9             unknown              0   Fri May 10 15:11:23 2024
devnull03-13            unknown              0   Fri May 10 15:23:38 2024
~]# 

When "JobPrivateAccess all" is set, it seems to allow user named "all".
In fact, when a user named "all" runs lpstat, it displays correctly.

~]$ whoami
all
~]$ lpstat -o
devnull01-9             user01               0   Fri May 10 15:11:23 2024
devnull03-13            user03               0   Fri May 10 15:23:38 2024
~]$

When "JobPrivateAccess all" is set, it should be allowed for all users.

According to scheduler/conf.c, not only JobPrivateAccess, but also JobPrivateValues, SubscriptionPrivateAccess, and SubscriptionPrivateValues ​​do not seem to support "all".
