[fprint] dbus + fprintd error

[Konstantin V. Gavrilenko]

Bastien,

the patch has applied fine, and fprintd seems to be working ok.

g_kos at dynomob ~ $ su -
** Message: debug on
Swipe your right index finger on UPEK TouchStrip
dynomob ~ # id
uid=0(root) gid=0(root)
dynomob ~ #


However, when I try to run it through the gdb, i don't get the "swipe the finger" prompt,
it goes directly to the password prompt.

g_kos at dynomob ~ $ gdb /bin/su

Another issue, I though that fprintd was suppose to allow simultaneous non interlocking access to the fingerprint device by several processes.
However, if i run one instance of su - and another one in the second terminal, the second goes straight into Password prompt.

Was I wrong in assuming that it can be used by several processes simultaneously?

yours,
kos
