Hello,

As a long-time Java web developer, I've now been doing clojure for a few 
days so there's a lot I don't get yet, but I do have an end-to-end working 
Compojure web application with a UI, JSON web services, and working 
form-based authentication using Friend - originally using the in-memory 
users 'database' from the demos.

So what I am doing now is trying to get user name and password validation 
going against a database table.

I actually managed to get this integrated and working as a Friend 
credential-fn.

The state my application in right now is that username and password 
combinations are properly validated against my database table. So I can 
authenticate, or not, correctly.

The only piece that is not yet working is to get role authorisations 
working according to the roles in my database table.

I just can't see how I'm supposed to map one or more namespaced roles to 
either a "roles" column value, or a roles join table in the database. 

The examples for Friend show roles like "::admin", "::user", and I use 
similar roles from more than one namespace - so what should I persist in 
the database to load those roles via my credential-fn, and how should I 
populate the :roles property from the result-set?

I feel like I'm really close to getting this fully working, but I've hit a 
road-block so any pointers would be greatly appreciated.

Regards,

-M.
