Is there a way to crunch for someone without knowing their account & password?

[Rattledagger]

Was wondering if there was a way to attach to a friends account and throw some stones his way without asking him for his account & password. I remember there was a way years ago using a persons CPID but I don't remember how to do it.

Hmm, CPID is only used to keep cross-project-stats aligned, and has never been usable to crunch as someone else.

In BOINC there's 3 ways to specify the account:
1: Joining a project by using email + password (or username + password then it comes to WCG). As part of joining a computer to a project, you'll get the account-key that is used in all further client/server-communications.
2: Use the "strong" account-key. The account-key is 32 hexadecimal characters long, meaning only numbers 0 - 9 and letters a - f.
3: Use the weak account key. This is acccount-number, a underscore and 32 hexadecimal characters that depends on the password.

With either #1 or #2 you've got full control of someones account, but with #3 you've only got limited access so can't example change team and so on.

So, if you want to crunch under someone else's account, you'll need to ask them to send their weak account-key.

To use the weak account-key, example make a file called account_boincsimap.org_boincsimap.xml and place it in your BOINC data-directory, that contains something like:

<account>
    <master_url>http://boincsimap.org/boincsimap/</master_url>
    <authenticator>123456_0123456789abcdef0123456789abcdef</authenticator>
</account>

After making the file, just re-start BOINC-client.

Note, the authenticator in the example is not a valid one, so it's a waste of time to try using it.
