PAM_SETCRED(3)		   App. Programmers Manual	       PAM_SETCRED(3)



NAME
       pam_setcred - set the credentials for the user

SYNOPSIS
       #include 

       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 users credentials.


       PAM_REINITIALIZE_CRED
	      delete and then initialize the users 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).


CONFORMING TO
       DCE-RFC 86.0, October 1995.
