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

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

treated as errors.
