    Hi Jochen,

    I think the scanner admin could have different wishes:
    1) a separate user/password list, may be a general or backend or device specific:
    sane.passwd, umax.passwd, microtec.passwd etc.
    2) usage of /etc/passwd (if the user is logged in on the local machine
    no test, if he is connected via net use /etc/passwd for authorization

    This should be selectable for each backend or device, so I suggest to
    set an option in the backend.conf that is read by the backend and
    passes the option to sanei_authorization_*

    eg:

    umax.conf:
    authorization system
    /dev/scanner
    authorization none
    /dev/sgd
    authorization sane.passwd
    /dev/sga
    authorization umax.passwd
    /dev/sgc
    authorization system, umax.passwd, sane.passwd
    /dev/sgd

    none => everyone can connect
    system => /etc/passwd
    sane.passwd => /SANEDATADIR/sane.passwd
    umax.passwd => /SANEDATA/umax.passwd

    or something like that

    Bye
    Oliver
