Ensure the user is logged in. In order to bind as the user, we use |
25 |
CatDap::Model::User, which uses Catalyst::Model::LDAP::FromAuthentication, |
26 |
which effectively requires calling $c->authenticate on every request. |
27 |
|
28 |
To do this, we keep the password, encrypted with blowfish, using the |
29 |
(for now), first 3 octets of IPv4 request address and a UUID string (stored in |
30 |
a cookie) as the key. To access the password, an attacker would need: |
31 |
- the first 3 octets of IPv4 request (not stored anywhere, but accessible |
32 |
in server logs) |
33 |
- the encrpyted password (only available server-side in the session variable) |
34 |
- the UUID key portion (only available on the browser-side in a cookie) |
35 |
|
36 |
So, if the user does "not exist", we authenticate them, if it succeeds we encrypt |
37 |
the password and store it in the session. |
38 |
|
39 |
If the user is logged in, we get the encrypted password from the session, decrypt |
40 |
it (we need to handle failure to decrypt it better) |
