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.
