To manage similar user accounts more easily, you can assign them to a group so that the user accounts inherit the properties, such as IT polices, software configurations, and WLAN configurations, of the group. You can assign a user account to multiple groups using the addUsersToGroup() method. To assign one user account to a group, you can use the addUserToGroup() method instead.

1. Invoke addUserToGroup().

   AddUsersToGroupResult result = coreWebService.addUsersToGroup(groupID, userIDs);

2. Check the result for errors and handle any errors.

   if (result.getAddUsersToGroupReturnStatus().getCode() != AddUserToGroupReturnStatusEnumType.SUCCESS) 
   {
           // handle any errors
   }
