pam_setcred - establish / delete user credentials
Синопсис (Synopsis)
#include <security/pam_appl.h>
int pam_setcred(pam_handle_t *pamh, int flags);
Описание (Description)
The pam_setcred function is used to establish, maintain and
delete the credentials of a user. It should be called to set the
credentials after a user has been authenticated and before a
session is opened for the user (with pam_open_session(3)). The
credentials should be deleted after the session has been closed
(with pam_close_session(3)).
A credential is something that the user possesses. It is some
property, such as a Kerberos ticket, or a supplementary group
membership that make up the uniqueness of a given user. On a
Linux system the user's UID and GID's are credentials too.
However, it has been decided that these properties (along with
the default supplementary groups of which the user is a member)
are credentials that should be set directly by the application
and not by PAM. Such credentials should be established, by the
application, prior to a call to this function. For example,
initgroups(2) (or equivalent) should have been performed.
Valid flags, any one of which, may be logically OR'd with
PAM_SILENT, are:
PAM_ESTABLISH_CRED
Initialize the credentials for the user.
PAM_DELETE_CRED
Delete the user's credentials.
PAM_REINITIALIZE_CRED
Fully reinitialize the user's credentials.
PAM_REFRESH_CRED
Extend the lifetime of the existing credentials.
