Both topics (and OpenID and OAuth) are massive hairballs anyway, but that starts ranging way too far afield for this website. Thanks for stopping by.

yeah, I get the distinction. I chaired some technical groups in the early 90s and the terms got flopped around with a few applications so I sometimes get a little careless when using the terms. My bad. ;-)

Right, login is just authentication – verifying who you are. File system permissions are authorization – are you allowed to do some such thing?

Check out the difference between OpenID and OAuth to get a big picture overview.

WP has an internal authorization system as well, the user roles. Most people pay no attention and simply log themselves in as administrator role. Sort of like logging into your unix box as root. Maybe not that dangerous, but same sort of thing in general.

Thanks–I do just mean login info. I’m curious what it’s actually doing with that info because it would then impact which user info one places in there. I’m gonna look at the source as it’s driving me nuts now. LOL

I can’t answer your question without some serious time poking around on the wp-hackers list and the wp source code.

My advice to you is scroll back through the commit history for the appropriate files, figure out who added that capability initially, correlate the commit with any activity on the wp-hackers list, then shoot an email off to the developer with any further questions.

That’s what I do: http://website-in-a-weekend.net/extending-wordpress/reverse-engineering-activation-hook-in-wordpress-plugin-api/

Also, from your question, I’m not sure what you mean when you write “credentials.” Authentication credentials are not the same as authorization credentials. If that’s not clear in your mind, that would be a good 3rd axis of attack on answering your question.

Once you get it all figured, I’d be delighted to consider running your findings as a guest post here on Website In A Weekend.

Thanks!

@dave so WP is not using those credentials for any part of the network activity? That’s what I’ve been wondering…it’s just sorta SUing as that user to set ownership of the files?

The short answer is WP needs write permission as the correct user. There’s really not much more to it than that.

What I’d like to know, is what is WP doing when it FTPs? If it’s an outbound FTP, then why does it need account credentials for the machine on which it’s running? If it’s telling another host to FTP back into itself, then where is it sending these credentials?
