Hello Mantis Plugin Community!

I am trying to figure out if I can create a Mantis plugin that would allow me to use the users, passwords, sessions, and to set permissions from my SMF forums so that a user only has to register once (with SMF) and can use that user name across all applications.

I have figured out what the MySQL queries would need to be to find the user and their password as well as the MySQL queries to set Mantis permissions (Reporter, Coder, etc.) but I am not familiar with the inner workings of Mantis and could really use some help.

Is it even possible for a Mantis plug to do this alternative method of authentication?

For reference I am working with Mantis 1.2.0rc2 for plugin support and SMF forums version 1.1.10.
