Amazon WorkDocs supports auto provisioning for all directory users

By GIXnews

Starting today, provisioning your WorkDocs site to all of your directory users is made easy. When provisioning your WorkDocs site, all directory users are provided a valid WorkDocs account, enabling each directory user to sign in and begin using full WorkDocs functionality as a Managed User without you having to manually activate each user. A Managed User has 1 TB of personal storage and can save files and collaborate with others on a WorkDocs site.
