Ensure the user is logged in. In order to bind as the user, we use |
| 29 |
CatDap::Model::User, which uses Catalyst::Model::LDAP::FromAuthentication, |
| 30 |
which effectively requires calling $c->authenticate on every request. |
| 31 |
|
| 32 |
To do this, we keep the password, encrypted with blowfish, using the |
| 33 |
(for now), first 3 octets of IPv4 request address and a UUID string (stored in |
| 34 |
a cookie) as the key. To access the password, an attacker would need: |
| 35 |
- the first 3 octets of IPv4 request (not stored anywhere, but accessible |
| 36 |
in server logs) |
| 37 |
- the encrpyted password (only available server-side in the session variable) |
| 38 |
- the UUID key portion (only available on the browser-side in a cookie) |
| 39 |
|
| 40 |
So, if the user does "not exist", we authenticate them, if it succeeds we encrypt |
| 41 |
the password and store it in the session. |
| 42 |
|
| 43 |
If the user is logged in, we get the encrypted password from the session, decrypt |
| 44 |
it (we need to handle failure to decrypt it better) |
