returning error code of script to module

[Chitrang Srivastava]

Hi,

Is their a way to return status code of an external script to the module.

Let me explain the problem:
PEAP-MSCHAPv2 with ldap and fallback is also there i.e. if ldap  server is
not reachable do local auth.
Now mschapv2 authentication with ldap is to be done using ntlm_auth  ,
So basically I want to know what ntlm_auth has returned ?
it actually returns "*Reading winbind reply failed! (0xc0000001) *" when
ldap is not reachable (net join has failed winbindd hasn't started)
ldap is reachable but userid/password incorrect *Logon failure (0xc000006d)
 *
*
*
For both cases Exec is return reject=1 as module return code, radius should
only do local authentication ldap is not-reachable and not when ldap reject
, but because exec output is always reject I cant distinguish the real
cause of failure.

Only way I can know what actually *ntlm_auth returns* ? if I know that I
can take decision in radiusd.conf.
