svnsync 1.8.0 fails if htdigest authentication is used

[Vadym Chepkov]

Hi,

After I upgraded to 1.8.0, svnsync process started to fail. I am using apache 
2.2.3. I suspect it's really serf's problem (1.2.1), 
but nevertheless I had to revert back to 1.7.10. Is this a known limitation?

Thanks,
Vadym
