    Command:

    pam_sm_setcred

    
    
    

    SYNOPSIS

           #define PAM_SM_AUTH
    
           #include <security/pam_modules.h>
    
           PAM_EXTERN int pam_sm_setcred(pam_handle_t *pamh, int flags, int argc,
                                         const char **argv);
    
    
    

    DESCRIPTION

           The pam_sm_setcred function is the service module?s implementation of
           the pam_setcred(3) interface.
    
           This function performs the task of altering the credentials of the user
           with respect to the corresponding authorization scheme. Generally, an
           authentication module may have access to more information about a user
           than their authentication token. This function is used to make such
           information available to the application. It should only be called
           after the user has been authenticated but before a session has been
           established.
    
           Valid flags, which may be logically OR?d with PAM_SILENT, are:
    
           PAM_SILENT
               Do not emit any messages.
    
           PAM_ESTABLISH_CRED
               Initialize the credentials for the user.
    
           PAM_DELETE_CRED
               Delete the credentials associated with the authentication service.
    
           PAM_REINITIALIZE_CRED
               Reinitialize the user credentials.
    
           PAM_REFRESH_CRED
               Extend the lifetime of the user credentials.
    
           The way the auth stack is navigated in order to evaluate the
           pam_setcred() function call, independent of the pam_sm_setcred() return
           codes, is exactly the same way that it was navigated when evaluating
           the pam_authenticate() library call. Typically, if a stack entry was
           ignored in evaluating pam_authenticate(), it will be ignored when
           libpam evaluates the pam_setcred() function call. Otherwise, the return
           codes from each module specific pam_sm_setcred() call are treated as
           required.
    
    
    

    RETURN VALUES

           PAM_CRED_UNAVAIL
               This module cannot retrieve the user?s credentials.
    
           PAM_CRED_EXPIRED
               The user?s credentials have expired.
