Copying a user
You can copy users from one group to another using the copy and paste options.
Click Users/Groups in the Administration window.
Right-click a user or group.
Click Copy.
Right-click the group that you are adding the user to and click Paste User/Group. The user is added to the list of members for that group.
In LDAP mode, it is not possible to copy a user because a user can not be a member of more than one group.
