Session authentification for perso Grid

Hello,

I use a JQuery Ajax inline Grid with a mySql database today, behind a .htaccess. I would like to use it with wordpress. Today the rows of my grid are my users and every users can add or delete datas.

I would like to use the session authentification of WordPress to manage the right to save or not each user when they clic on the row. Well, WordPress is able to manage the righr of each users and I would like to implement this on my grid. The question is, how wordpress works when we need to integrate a page in the wordpress “world”.

Is there any tutorial for that ?

Thanks
John.
