When you apply a User names filter, the Default value column displays a field in which you can enter one or more specific user names. If you are using Forms authentication, you must enter the user name exactly as it exists in the database. If you are using Windows authentication, you must enter fully qualified user names (including the domain name).
Alternatively, you can use the Find users link to select user names rather than typing them in.
The Find User page consists of two panes, the Search pane and the Search Results pane. The options in the Search pane allow you to search for user names that contain or start with specific characters. By default, 10 user names are returned, but you can change this number. For example, you can restrict the search to find only 5 users or expand it to find 30 users.
The search returns an alphabetical list of user names that satisfy the search criteria. If the number of found user names exceeds the specified number of search results, this list is truncated as needed. To include more user names in the search results, you can rerun the search using a larger number of search results.
The results of a search appear in the Matched User Names field in the Search Results pane. You can then select the user names you want to include in the report and add them to the Selected User Names field. In addition, you can repeat the search using different criteria, to select additional users to include in the report.
Note: You can search for all user names by leaving the search characters field blank. Users for which no tracking data exist are not included in the search results.
