[Spice-devel] [spice-gtk v5 1/2] Add SpiceSession:use-system-ca-file property

Tue Nov 12 07:20:02 PST 2013
This property indicates whether to look into the system
CA database when validating certificates in a TLS connection.
This property defaults to TRUE, but is automatically set to
FALSE when SpiceSession:ca-file is set.
