Hi All. In our environment (squid-3.0.STABLE13 + CentOS + ntlm + kerberos + win 2k3 ADS), new msn messenger was not working. So we forced the users to use msn messenger version 8.1 which was working. But from today morning onwards, we found that, for all the users when they try to login to MSN, then an mandatory update screen is poping up. Without updating this msn, it is not allowing to login. So now we are forced to find a way to allow the new msn messenger... Really expecting any favourable hints...
