DIGEST-MD5 on HTTP webserver

[Nil Croustillac]

Hi all,

It's been a while now I am trying to implement the Digest authentication
with the Cyrus SASL library and I don't understand how to proceed.
I am using the version 2.1.25 and only support digest mechanism, here is
the desired behaviour (which doesn't work)
 * initial call from client:
     1. sasl_server_new()
     2. sasl_setprop(http_request)
     3. sasl_server_start()
     4. send the challenge provided by previous function
     5. sasl_dispose
 * second request from client (containing authentication information):
     1. sasl_server_new()
     2. sasl_setprop(http_request)
     3. sasl_server_start("clientin = authentication http header")
     3. I tried instead sasl_server_step but it doesn't work either.
     4. sasl_dispose

I expect the third step to authenticate the user with the `clientin` I
provide - from http request header - but I only get a floating point
exception :(.
Could you please help me with what would be the right process ?

Regards,
Nil.
