In the basic authentication approach the userid and password
are concatenated with a ':' between them, base64 encoded, then
placed in an HTTP header to send to the server.

Obviously, the server will have trouble differentiating between
the ':' in the username and the one separating the user name
from the password.

In other words, this is an artifact of BASIC authentication.
