man pam_setcred (Fonctions bibliothèques) - set the credentials for the user
NAME
pam_setcred - set the credentials for the user
SYNOPSIS
#include <security/pam_appl.h> int pam_setcred(pam_handle_t *pamh, int flags);
DESCRIPTION
pam_setcred
This function is used to establish, maintain and delete the credentials of a user. It should be called after a user has been authenticated and before a session is opened for the user (with pam_open_session(3)).
It should be noted that credentials come in many forms. Examples include: group memberships; ticket-files; and Linux-PAM environment variables. For this reason, it is important that the basic identity of the user is established, by the application, prior to a call to this function. For example, the default Linux-PAM environment variables should be set and also initgroups(2) (or equivalent) should have been performed.
VALID FLAGS
- PAM_ESTABLISH_CRED
- initialize the credentials for the user.
- PAM_DELETE_CRED
- delete the user's credentials.
- PAM_REINITIALIZE_CRED
- delete and then initialize the user's credentials.
- PAM_REFRESH_CRED
- extend the lifetime of the existing credentials.
RETURN VALUE
On success PAM_SUCCESS is returned, all other return values should be treated as errors.
ERRORS
May be translated to text with pam_strerror(3).
