Description

Allows you to specify which extensions are not subject to the blacklist. A blacklist value of * means all extensions are blacklisted and users can only install extensions listed in the whitelist. By default, no extensions are whitelisted. If all extensions have been blacklisted by policy, then the whitelist policy can be used to allow specific extensions to be installed. Administrators should determine which extensions should be allowed to be installed by their users. If no extensions are whitelisted, then no extensions can be installed when combined with blacklisting all extensions.
