NAME

       pam_setcred - modify/delete user credentials for an authentication service

SYNOPSIS

       cc [ flag ... ] file ... -lpam [ library ... ]
       #include <security/pam_appl.h>

       int pam_setcred(pam_handle_t *pamh, int flags);

DESCRIPTION

       The pam_setcred() function is used to establish, modify, or delete user credentials. It is typically called after the user has been authen-
       ticated and after a session has been opened. See pam_authenticate(3PAM), pam_acct_mgmt(3PAM), and pam_open_session(3PAM).

       The user is specified by a prior call to pam_start() or pam_set_item(), and is referenced by the authentication handle, pamh. The following
       flags may be set in the flags field.  Note that the first four flags are mutually exclusive:

       PAM_ESTABLISH_CRED	       Set user credentials for an authentication service.

       PAM_DELETE_CRED		       Delete user credentials associated with an authentication service.

       PAM_REINITIALIZE_CRED	       Reinitialize user credentials.

       PAM_REFRESH_CRED 	       Extend lifetime of user credentials.

       PAM_SILENT		       Authentication service should not generate any messages.

       If no flag is set,  PAM_ESTABLISH_CRED is used as the default.

RETURN VALUES

       Upon success, pam_setcred() returns  PAM_SUCCESS. In addition to the error return values described in pam(3PAM) the following values may be
       returned upon error:

       PAM_CRED_UNAVAIL 	       Underlying authentication service can not retrieve user credentials unavailable.

       PAM_CRED_EXPIRED 	       User credentials expired.

       PAM_USER_UNKNOWN 	       User unknown to underlying authentication service.

       PAM_CRED_ERR		       Failure setting user credentials.
