SugarCRM - how to customize user management tools?

I'm new to using SugarCRM. I want to have a users page that does the following:

1. Allow a user to create sub-users, and each sub-user can then create additional sub users
2. Display users in an expandable and collapse-able hierarchical tree structure
3. Add more attributes to each user
4. Any newly created user should be able to login to SugarCRM using suga开发者_如何转开发r's existing authentication.

Does anyone know how to do this? Or if they can recommend tutorials/resources for me to study?

John, you will need a one to many relationship based on a custom module. One user can create a sub user.

So begin by defininig that module and relationship inside of SugarCRM studio. Once this is defined if you try to throw a subpanel on the Users module you will notice an add / delete / edit button, allowing you to add / delete sub users.

To add more attributes to your user you simply go into studio, select that module and add _c (custom fields) to the corresponding table. You can add custom text, int, long, float, varchar, etc fields.
