Licensing 3.2 Beta 2 NE
NOTE - This applies to 3.2 Beta 2 or LATER releases of the Zimbra Collaboration Suite, and only applies to the NETWORK EDITION. The open source version requires no license file
Zimbra Licensing is for the Network versions. Its purpose is to enforce agreements we have with our customers.
Licenses are files that are installed once per deployment. The license constrains the number of users that are allowed to be in use and an expiration time after which some network features are lost and no users can be created.
3.2beta2 and 4.0RC1 shipped with trial licenses embedded in them. 4.0.0GA did not embed a trial license, but does require one to run.
