As you mentioned, Ajax techniques in WordPress will be helpful for me.
I’m really appreciate for your advice.

Thank you for reply.

Actually, authentication is processed by wordpres plugin by connect sqlserver directly.
So wordpress’s authenticate was finished. But other system using sqlserver doesn’t know it.

So my approach is sharing login information by browser’s local storage. But as you said, this is handled by browser not by php at wordpress.
To make Ajax page, and invoke it at wordpress plugin is the best for that?

I really appreciate you for a advice.
Without your help, I might go to the painful road.
Now I can know what I have to do.
Thank you.

@bcworkz,
Thank you for your reply.
If not your reply I might choose very painful course.

Can I ask one more question?
Wordpress has a wp_users table which stored user information.
If I customize login form with wp_authentificate which authentificate with another system, which way is the best for handling wp_users table?

From ERD, wp_users primary key is the FK of wp_usermeta, wp_comments and wp_posts. So should I replicate user information from other system’s user table?

If you know the best practice for this case, would you share me?
Thanks again.
