Sohaila,

Strictly speaking, there is no "CollabNet ViewVC", so I must guess that you
are referring to something like "ViewVC as distributed with CollabNet
Subversion Edge" or somesuch.  Perhaps you could clarify?

In any case, ViewVC does not handle its own authentication -- it merely
piggybacks on the authentication challenges and state offered by its host
server, the Apache HTTP Server.  If by "login through collabnet viewvc" you
mean that you visited a ViewVC page, got a popup prompt for a username and
password, and then were able to continue on through to ViewVC, then what you
have done is not so much login to ViewVC, but *more* like login to Apache
for the authentication realm that it is configured to use for ViewVC.
ViewVC has no record of a "login" or "logout" -- all it knows that sometimes
when Apache invokes ViewVC, it says, "By the way, I have a username that
seems to apply to you", and sometimes it doesn't.

Most of the time when folks who are used to seeing that authentication
prompt stop seeing it, it's for one of two reasons:

1.  Their browser has cached the last successful username and password they
provided for the authentication realm used by ViewVC, and is now offering
that information to Apache without bothering to prompting the user.  (Try
closing your browser or explicitly clearing its cached authentication
session information).  Or,

2.  The Apache HTTP Server's configuration has been modified to no longer
require authentication credentials when visiting the URL space served up via
ViewVC.  If Apache doesn't require auth creds, ViewVC doesn't care -- it
just operates in a sort of "anonymous user" mode.

We'll probably need to get more details of the experiences you previously
had and are now having in order to better understand your specific situation
and prescribe and explanation and solution.  What more can you tell us?
