[PATCH] digest auth not working in 2.5-stable

Hi,

Digest Authentication in Squid 2.5 stable1 and Squid 2.5 Stable1
20030204 is broken. Using src/auth/digest/auth_digest.c, once a user
has attempted a login further attempts succeed or fail based on the
success of the first attempt. This is because the credentials_ok flag
is not reset between attempts.

The attached patch fixes this problem.

Please CC me into replies, as I am not subscribed to squid-dev.
