You must have configured at least one group before you can configure users.
If necessary, click Check-out to open the group information for editing.
Enter the user's name.
Enter a username that will be used for login.
Enter a password for the user.
Enter the user's email address.
For Pessimistic lock mode users, the address you enter will be used to send a reminder to the user in the event that he or she forgets to check-in an object.
To give the user the ability to configure other users' permissions, select the checkbox.
Enter the user's additional email address.
Select the groups to which the user belongs.
When associating users with groups, consider that the access permissions granted to a user are by default those of the most broad-ranging group to which the user belongs. For example, if you have already configured a user as belonging to a group that has read-write-delete permissions for photos, you will not alter the user's access permissions by subsequently adding them to a group with read-only access permissions for photos.
When you are done, select Save or Check-in (according to your selected lock mode) to save your user configuration.
