Apparently there are two implementations for pam_cap. One supports the
other doesn't.

Good luck.

Do you have any y reference for your information?

If you want this type of feature, set CAP_SYS_NICE to the group audio
that you are referring.
??? How can I grant capabilities to a group? I thought capabilites where either given to
a user (via /etc/security/capability.conf) or to a binary (by means of setcap).

AFAIK, pam_cap support users and groups. Apparently there are two implementations for pam_cap.

other doesn't.
No. That's wrong. pam_cap doesn't support caps by group, your second link points
the pam_capability module. IIRC that was only ever available in OpenSuse. The git log
(single line ...) of that repository doesn't really make me want to integrate it into
a seccurity
service.

If that feature is really important for you, you can always patch
pam_cap.c from lipcap2.
It seems like a nice feature to have, IMO.
