Question
Keeping authentication across subdomains (different servers)
We currently have a main website that performs authentication (www.domain.com) using mod_auth_mysql against a mysql database. This website stores a cookie as well with user ID information.
We are setting up an application on a different server that is a subdomain (app.domain.com). The application has its own user table in its database but supports external authentication against a separate database using REMOTE_USER.
The problem is that since the application installation exists on a totally separate server, REMOTE_USER does not exist when the user browses from the main site to the application site. However, the domain cookie is readable.
I have code that parses the cookie, finds the user ID, does a mysql query and determines the username of the user. Is there a way, using PHP, to then use that username to populate REMOTE_USER so that authentication will be bypassed since the user has a valid cookie for the domain? Or any other way to utilize the cookie to bypass http authentication? We want the browsing experience for the main website and the application to be seamless.
Thanks!

yea, I really should awake up before answering. Kinda read that part after I posted.
Anyway it's like the signup I use on a site that changes subdomains.
I set two domain wide cookies, one with the username, and the other a unique random number I called 'checksum' that when run through a MD5 will match a number stored in their user profile.
to verify them
select first_name from users where user_id=$user_id and login_checksum=MD5($_COOKI
NOTE: Both MySQL and PHP have MD5 functions. They do NOT return the same answers. Select one and always use it. There was also some talk about PHP5 MD5 function being changed. This won't be an issue if you set the checksum as each user logs in.
Michael
Well, as I said, both domains can read the cookie, so that's fine.
But the new app wants to read from the REMOTE_USER server variable, which gets set when people log into the main domain ... but is null when they switch to the app domain. So I'm looking for a way to set REMOTE_USER server variable, if it's even possible. I know who the REMOTE_USER should be since I can read the cookie and extract the username of the person from it; I just need to be able to set it.

I believe your question for seemlessness all boils down to:
Can you set the values of $_SERVER['PHP_AUTH_USER'] , $_SERVER['PHP_AUTH_PW'], and $_SERVER['AUTH_TYPE'] ?
ie:
is $_SERVER['PHP_AUTH_USER'] = $_COOKIE['username'];
allowed?
This answer I dont know...
