According to the download page, there is supposedly no difference between the community version of Alfresco and the enterprise version in terms of functionality.
However, I'm noticing comments in the config files that read "Enterprise version only".
The reason I'm asking is that I'm trying to get NTLM passthrough to work, but it appears to be unimplemented, and I noticed the above mentioned comments in the NTLM portions of web.xml. I don't want to waste any more time trying to make it work if it's not possible.
