The pam_sm_authenticate function is the service
module's implementation of the
pam_authenticate(3) interface.
This function performs the task of authenticating the user.
Valid flags, which may be logically OR'd with PAM_SILENT, are:
Do not emit any messages.
Return PAM_AUTH_ERR if the database of authentication tokens for this authentication mechanism has a NULL entry for the user. Without this flag, such a NULL token will lead to a success without the user being prompted.
