PAM_CAP

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

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
