I have noticed a problem that I cannot seem to fix. Using password authentication works fine MOST of the time, but there are certain passwords that don't seem to get passed thru squid properly. Length is not the issue, and the the authentication program is working fine. Running the same user/password combination thru the authentication program separately works fine.
As best as I can tell, squid is stripping or not allowing meta characters thru to the authentication program. It apparently worked in 2.4, but doesn't work in 2.5. Have I found a bug, or a deliberate change? --Mark
