Funambol Moz Client + Mooha -> Error 407

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use Funambol Mozilla sync client
2. Launch synchronization
3. Get 'Error: Can't get your account. Please check your server location, 
username or password.'

What version of the product are you using? On what operating system?
Windows XP (same with Arch Linux up to date)
Funambol Mozilla Client (1.0b4+jm-tb6-dev4) on Thunderbird 6.0x with Calendar 
1.0b5
Mooha 0.3b

Please provide any additional information below.
I did a few tests (using a bad user / password / host), and it seems that the 
error is slightly different when the user/password/host is wrong.
A few wiresharking gave me the content of the XML exchanges, I put them as 
attachments (A*.xml are files from my computer ; B*.xml are files from the 
server). I simply removed the real server url from the logs. User and pass are 
set to mooha:mooha for the tests (so you can check the encoding, base64 or md5).
If you want to try things, I can give you (in private mail) the uri to the 
server.
There are datas actually on the server, from a Nokia 5800XM (syncs seems to go 
fine with my phone).

A few more details : you can find the Thunderbird extension at 
https://mozilla-plugin.forge.funambol.org/ds/viewMessage.do?dsForumId=553&dsMess

The error occurs at any time, in every situation (two way sync, full resync, 
first sync, any other later sync...).
