PAM_SETCRED(3) App. Programmers' Manual PAM_SETCRED(3)
pam_setcred - set the credentials for the user
int pam_setcred(pam_handle_t *pamh, int flags);
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 member-
ships; ticket-files; and Linux-PAM environment variables. For this reason, it is impor-
tant 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.
initialize the credentials for the user.
delete the user's credentials.

On success PAM_SUCCESS is returned, all other return values should be treated as errors.
May be translated to text with pam_strerror(3).
