My company is considering using Alfresco, and we will soon install a test version.
We would like to use Oracle as storage back-end, and use LDAP to authentify users on our Active Directory. Does it mean that we need the "Enterprise" version of Alfresco?
No it does not! All functionality between the Community and Enterprise versions of Alfresco is identical. Purchasing the Enterprise version gives you a supported product which has been certified against specific platforms - and so features additional bug fixes and therefore stability and performance on those platforms.
