Local login

1. A brief description of what is proposed

Allow authorised Raven users in an institution to create local logins for short-term visitors.

2. An explanation of how it would be useful

Would allow short-term visitors to use Raven authenticated services.

3. One or more suggestions of how it could be implemented

Web form for authorised users allows registration of local user (name, position, home institution, contact email/tel). Result is a page much like the UCS pre-arrival registration system so user can collect their own password.

To be really nice Raven would need to understand that temporary users can only access pages in a specific domain... unless an institution can specify username (chemtemp01, etc.) then an institution can add those Raven IDs to Raven access control lists. I think it would be easier if Raven did this work.
