pam_cap - PAM module to set inheritable capabilities

PAM_CAP(8) Linux-PAM Manual PAM_CAP(8)

NAME

pam_cap - PAM module to set inheritable capabilities

SYNOPSIS

pam_cap.so [config= /path/to/capability.conf] [debug]

DESCRIPTION

The pam_cap PAM module sets the current process' inheritable capabilities.
Capabilities are read from the /etc/security/capability.conf config file, or alternate file specified with the config= option.
The module must not be called by a multithreaded application.

OPTIONS

config=/path/to/capability.conf
Indicate an alternative capability.conf style configuration file to override the default.
debug
Print debug information.

MODULE TYPES PROVIDED

Only the authentication module type is provided.

RETURN VALUES

PAM_AUTH_ERR
The user is not known to the system.
PAM_IGNORE
No capabilities found for this user.
PAM_INCOMPLETE
Indicates a PAM-Conversation failure.
PAM_SUCCESS
Capabilities were set.

FILES

/etc/security/capability.conf
Default configuration file

EXAMPLES

Nearly all applications/daemons which use PAM for authentication contain a configuration line: @include common-auth. Thus, to set inheritable capabilities in all of these applications, add the following as the last line to /etc/pam.d/common-auth
auth optional pam_cap.so
To set inheritable capabilities for a user in a specific application, or in application(s) which do not @include common-auth, add the line below to the application-specific file; e.g. /etc/pam.d/myapp
auth optional pam_cap.so

SEE ALSO

capability.conf(5), pam.d(5), pam(7).
