Hi, Actually I am working on a project in which we are migrating from 3.x to 4, so Please tell me the difference in versions and also give me information that how we can use active directory of 4.0 effectively as we are having CIFS and Kerberos feature in 3.x, And how this active directory can be helpful in our implementation. And I am also having a question as we are using 3.x so only because of active directory in 4.0 we should migrate from 3.x to 4.0 or is it having some more additional features that can be useful in future. Please reply as soon as possible.
