An administrator can check license information to determine how many users are authorized and registered to use them.
- Select the Administration tab in the Workbench Ribbon.
 
- In the Security band, click Check Licenses.
The 
License Check
                    dialog appears.

The dialog reports the number of authorized and registered users for each
                        license type.
Note: The
                        sum of these three authorized licenses is the number of Astoria Users your
                        organization is authorized to create in Astoria. (You are also provided one
                        additional authorized user which is used to run the Astoria
                        Services.)
Important: If your registered users count exceeds your authorized users
                        count for authoring licenses, not all registered users will be able to edit
                        structured documents. See 
Authoring Licenses and License Groups and 
Determining Who is Authorized to Edit.
 If this occurs,
                            remove a sufficient number of users from the authoring license group, or
                            purchase additional licenses to meet your needs.
 
Note: If either of
                        your authoring license groups contain groups, and a user is a member of
                        multiple groups that are included in the license group, should you wish to
                        remove that user's authoring capability, you may need to remove that user
                        from all of these groups.
Note: The number of registered
                        users for the Reviewer license (Non-Structured Document License) equals the
                        number of users in your repository. The number of authorized users equals
                        the Reviewer license count you have purchased. If more than the authorized
                        number of users attempt to log in to Astoria (either the Workbench or
                        Reviewer interface), some logins will fail. See 
About Reviewer Licenses.
