Microsoft Dynamics CRM - password hashing algorithm

Question

I work at a University and our application for admissions is a product that is built on top of Microsoft Dynamics CRM 4.0. (The application is called 'Recruiter'.)

There is a table with usernames and hashed passwords. I would like to write an app (in Ruby on Rails) that queries the username and hashed password to validate a login.

Unfortunately, I do not know how the hashed password is generated. It appears to be a Base64-encoded MD5 checksum.

I have read elsewhere that the hashed password is generated using a combination of:

1. the plaintext password
2. the primary key of the record (a UUID string, not an integer)
3. the database server name

I have tried variations of this to create a hashed password that matches the record in the database, but I cannot get this to work.

Can anyone tell me how to generate a matching hashed password from a plaintext password?

Thank you!

This is not a customization based on the capabilities of Dynamics CRM. It looks like Dynamics CRM is used as a framework for this. You have to contact the original creator of this application.
