I don't know exactly what rhost means here. Would guess something like Remote-
Host?
>From the logical Point of View. PAM is invoked from saslauthd, the Library
sends in behalf of the Application only 4 things to saslauthd. The Username,
Realm, Servicename and the Password. Nothing else. So there is just not enough
data in saslauthd to give something about the remote Host to PAM.
You would have to change the protocol between the SASL-Library and saslauthd
to pass something about the Remote End to saslauthd and then change the PAM-
Stuff in saslauthd to set the RHOST Data.
