[reSIProcate] Authentication+Authorization bugs

[Scott Godin]

I've modified ServerAuthManager to not challenge ACKs or CANCELs - still
looking into the 2nd issue.  : )

Hi,

I found a bug in DUM:

ServerAuthManager tries challenging ACK requests.
Another problem is that Proxy-Authorization header isn't sent within ACK
requests as it should.

According to the RFC:

   Under an authentication scheme that uses responses to carry values

   used to compute nonces (such as Digest), some problems come up for

   any requests that take no response, including ACK.  For this reason,


   any credentials in the INVITE that were accepted by a server MUST be

   accepted by that server for the ACK.  UACs creating an ACK message

   will duplicate all of the Authorization and Proxy-Authorization




   header field values that appeared in the INVITE to which the ACK

   corresponds.  Servers MUST NOT attempt to challenge an ACK.

I'll try to resolve the bug but I'm sure you'll do it faster and better
than me...

Thanks,
Elberg Meir.
