If in hcid.conf I use these lines:

        auth enable;
        encrypt enable;

then when I do sdptool browse or sdptool search, it keeps prompting me
to bond with every Bluetooth device that it discovers.  This does not
make sense, because the whole point of service discovery is to decide
what device you want to connect to, before having to bond with it.  If
the device was requiring a bond before answering an SDP query, fine,
but the devices I have tested with do not - they will answer SDP
queries just fine without a bond, as long as I have commented out those
two lines in hcid.conf.  Maybe this is a bug - IMO bluez should
probably ignore those settings for SDP, and always do SDP insecurely. 
Otherwise "sdp search" becomes very impractical.  At my office often 20
or more devices will be involved in such a search, belonging to various
coworkers, some of whom I have not met, and I certainly do not want to
bond with all those devices; but I also do not want to turn off
authorization completely just so that I can do sdp queries.
