Site Login pass through

[lenwood]

Hi All,
I'm creating a website that contains some tools to be used by a community. One is a wiki, and the other is a groupware application. Could someone describe a way for there to be one login for the site, and have those logins pass through to the others?

The goal is to have one login for both tools (wiki & groupware). I know that I'll need to create matching usernames & passwords for both apps.

Let me know if this has been explained elsewhere.

Thanks,
Chris

All on the same site? Set a cookie. If they are on different domains or subdomains you will have to pass a variable via query string when moving from one to the other, as cookies can only be read on the specific domain they are set on.

- encrypt user id
- encrypt password
- set a cookie for each. Use a SESSION cookie that expires when the browser is closed - low maintenance

Your login sub will look something like

if (login_fields) { use login field values to set u and p }
else {
read cookie
decrypt values
use decrypted values to set u and p
}

if (no u and p) { return to login }
look up matching u and p in DB
if (found) { go to requested page }
else { return to login }
