# In very old (e.g. 1.1.54385) versions of ClickHouse there was a bug in Poco HTTP library:
|
|
# Basic HTTP authentication headers was not parsed if the size of URL is exactly 4077 + something bytes.
|
|
# So, the user may get authentication error if valid credentials are passed.
|
|
# This is a minor issue because it does not have security implications (at worse the user will be not allowed to access).

# In this test we do the opposite: passing the invalid credentials while server is accepting default user without a password.

# And if the bug exists, they will be ignored (treat as empty credentials) and query succeed.
