I'm not sure if this is the right place to report any issues. I tried to install a small multi-server ZCS NE on Centos 6.2 and found I was unable to log in at all. This stopped me from evaluating the product.
The login page appeared but the correct user and password were never accepted, and intermittently a message about the browser needing to accept cookies was shown (the browser does allow cookies).
There may have been a proxy configuration issue but somehow I doubt it. The login page was shown correctly.
I'm continuing with a single machine install to see if I can get it to work. A shame because I was partly interested in the UI changes but also because I wanted to try out the multi-master LDAP configuration.
