you can get the ACL handle through getsockopt() and then open an HCI raw
socket and send the command. But I think the Authentication_Requested
command will also fail due to limited permissions.

For some time I thought to add the possibility to do authentication and
enable encryption through the socket interface or L2CAP and RFCOMM. At
the moment I haven't decided if I wanna do that with setsockopt() or
with ioctl(). Feel free to suggest something.

Do you think a pairing/bonding application is needed for Linux? If one
side requests the authentication we will handle it through PIN helper
and the rest is handled inside hcid. Deleting the link key is the only
job we might need an application for.

Regards

Marcel
