Hi, I need some help with digest authentication. When I uncomment those lines in ser.cfg, the register msg stops to work. In the trace, see below, you can see the nonce being sent in the re-register msg, but the server still responds with 401 Unauthorized. I've tried with both 0 and 1 in the www_challenge. Without the digest authentication the register works fine. Thanks in advance, //Magnus ser.cfg (ser 0.8.12 running on a Fedora box.
