Automatic login to external third party PHP applications (eXtplorer)

[Beuy]

Hey yo,

 

I am designing a simple login script that will allow users to have the same login and password yet access a number of different PHP third party applications. I have enough knowledge to create this user authentication application and have done so in the past, however I am having difficulty in discovering how to automatically login to the third party programs.

 

The program is intended to work as such:

1. User log's into application and is given a number of links (one of which is to a file management program called eXtplorer)

2. When a user clicks on the link, they are taken to the external application already logged in, instead of having to type the username and password.

 

I thought I could do this by discovering what the variables external applications (eXtplorer) use for the login process, however I am quickly discovering that my skills and knowledge with PHP are not as high as I thought as I cannot discover where exactly this information is within the program.

 

If anyone could provide any assistance to me with this it would be greatly appreciated.

 

With thanks,

 

Beuy
