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 creden-
tials of a user. It should be called after a user has been authenti-
cated and before a session is opened for the user (with pam_open_ses-
sion(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 vari-
ables 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).
