[reSIProcate] realms in repro proxy

[Rohan Mahy <rohan@xxxxxxxxxx>]

Hi,

Currently the repro web admin effectively ignores realms by setting the 
realm to the domain name when you add a user.  I understand that you 
might have a user who has one set of Digest credentials (username, 
password, realm) but has multiple AORs (possibly in different domains). 
 This would indicate a 1:n relationship between digest credentials and 
an AOR.  However, for some AORs (like sales@xxxxxxxxxxx) it could be 
authenticate with one of several digest credentials. This indicates an 
n:n relationship.

I would like to punt on this for release 0.1, but I also want to 
explore what would be necessary to make this work.  Expressing this 
kind of relationship with a database means that you need to have a 
table of credentials, a table of accounts, and a table that expresses 
the valid authorization relationships between the two.  Getting the 
admin UI to do this correctly without making it harder to use in the 
"ordinary" case could  be tricky.

thoughts welcome.

thanks,
