Connman does only support two phase authentication via config files.
These config files reside in /var/lib/connman/ and are watched by
the connman daemon. Unfortunatelly, connman does not support per
session/user config files, so for simplicity's sake, we modify one in
/var/lib/connman. With these changes, econnman manages a single file
(/var/lib/connman/econnman.config), to which the user running it needs
write access. By default the (empty) config file shipped with this packages
has write permissions set for the group. Packagers might want to change the
owner/group to root:users after installation or come around with a more
sophisticated approach.
I disabled the check for the presence of the old bindings
in configure.ac as the new bindings does not provide a pc file,
and because it now works with both versions,
but I highly raccomend to switch back from autotools to distutils.
