ASP.NET Login Page & API Calls

I represent a hosted software company in need of a single script translated from PHP into ASP.NET We are a SaaS company, provide single sign-on for some of our customers. They host a small piece of software inside their firewall that handles the interface between our API and their back-end authentication. This is often LDAP, but it could be anything, which is why we make them host it. We provide a sample implementation in the language of their choice, they customize it to meet their needs.? The following is a brief description of what would happen: 1) When the user hits the script, it displays a simple login form. 2) After submitting the form, the script attempts to bind to an LDAP server as the user. It does a search to find 5 attributes. 3) If the LDAP bind or search fails, the user is redirected to the original form with an error message. 4) If the bind and search succeed,? a request is made to our login API (over HTTP) passing some hard-coded variables (such as the system ID) as well as some of the retrieved attributes 5) The login API will give one of three applicable responses: ? ? ? ? a) Success. A one-time token is return and the user is redirected to a fixed URL with the token appended. ? ? ? ? b) User not found error. The script attempts a second call to a "create user" API, followed by another login attempt and (a) above ? ? ? ? c) Other errors. Displays a message same as #3. I need to provide a sample to a new client ASAP. I have this exact script written in PHP.? Ideally this will answer most questions for the accepted bidder.
