Auto-login into vendors ASP.Net application in my own environment
<p>I've got an Intranet that I manage, and we've just purchased some vendor's system that has no out-of-the-box LDAP/AD support. I think it's an ASP.Net application (there's a form on the login.aspx [hint1] that has id="aspnetForm" [hint2]), and I thought, in my perfectly-run imagination, that all I had to do was pass users credential in as parameters to the login page (I've injected their usernames into the vendor's database, and I can manually log in fine with those), and it just worked. Not so.</p>

<p>Uri looks something like this ; http://[apps_domain]/Controls/CtlLogin.aspx</p>

<p>I have no access to this ASP.Net environment, I can only access it through URI's, however I've got full access to another server on the environment on which I could run various scripts, preferably PHP (as we run a few other apps in PHP, and we've got people with those skills).</p>

<p>Is there some default way that ASP.Net delivers simple login to their apps? I'm using NTLM and AD elsewhere to validate the credentials, I just need to inject these into the ASP.Net app. I expected this to be simpler ... :)</p>
