Name
pam_cap - PAM module to set inheritable capabilitiesSynopsis
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
