My wife and I have separate accounts on our iMac. I often have need to access the iMac's screen from my Macbook Pro--sometimes to access something on my screen, sometimes to access something on her screen. Both computers are running Lion.
Is there any way to disable (or otherwise get around) the requirement of having to log in to the iMac user's screen when trying to establish a screensharing connection? I just want it to work the way it did in Snow Leopard, where you just establish a connection and a login is never required.

Think for a minute. If you don't log in, how is the computer supposed to know which account to connect you to, yours or your wife's? Snow Leopard could only support sharing one user screen at a time. Lion can have multiple people using the GUI and logging in is how it knows.

I understand that...I'm asking whether there's a way to simply log in to the currently active user, or at least disable the requirement that the logged in user manually verify the incoming screensharing request.

You don't need a password if both Macs are currently running with the same user ID and password.
Other than that, I don't think it's possible, because you are essentially asking to turn off very basic Unix security and user account features.

I don't understand why that would be so. In Snow Leopard, my wife could be logged in as her own ID down on the iMac, and I could connect to her screen via Screen Sharing while logged in as myself on my Macbook Pro. This procedure in Lion now requires a password. It's clearly a new "feature" of Lion, not a basic security feature. Since it's something Lion-related, I'm thinking there has to be some way to change its behaviour, or at least disable it.

As turtle said, you're asking for a way to bypass basic unix security and I doubt that it's possible. You even described it yourself, in Snow Leopard your wife was logged in yet you could see her account without a password. That's a security flaw, and apparently Apple has fixed it. Asking for a password before accessing a computer account is not too much to ask.

I suspect that before Lion, Screen Sharing used basic VNC w/o authetication.
Possibly, Lion is using a SSH tunneled VNC, and therefore, requires authentication. It's not the Screensharing par se, but the encrypted tunnel that needs a password.
Just speculation on my part though.

You are all misunderstanding the problem. He's not talking about removing authentication to establish the screen sharing connection. He's talking about the login screen that is presented for the new per-user screen sharing once the screen sharing connection is started. Lion now supports virtual sessions. A user can now start a screen sharing session and log into their own account while a different user is sitting at the Mac using their account.

I'm not sure that's true.
The OP talks about "disable [...] the requirement of having to log in".
I interpret "log in" as authentication.

Here is the Logic (how I observe it) behind Lion Screen Sharing:
1) If BOTH active users (both Macs) are the SAME user ID, you get connected W/O a password (authentication)
2a) If you are USER1, and USER2 is active on the other Mac, you need to enter their password to do Screen Sharing of USER2
2b) If you are USER1, and USER2 is active on the other Mac, but a USER1 exists on the other Mac, you can Screen Share to USER1 ("Virtual Screen") w/o a password.
It seems the only "provision" to log in w/o authentication (but using a different user) would be using Apple ID. I have never tried that, so you might want to check it out.

Also, if you use ARD (Apple Remote Desktop), you can allow certain users access to a Mac, and don't need any passwords for Screen Sharing.

Must have been a DB goof because I never visit the PWL. I was responding in this thread.

Go to System Preferences, click on Sharing, then click on Screen Sharing, then click on Computer Settings. I think what you are looking for is Anyone my request permission to control the screen. The VNC settings is also in that same box.

Hi, sorry I haven't responded to this in a while, got busy IRL.
I don't think the Lion screen sharing logic speculated upon here is correct. At least, 2a isn't, because it additionally requires USER2 to verify the incoming request (see below).
I guess I really didn't make my question clear (my bad). What I'm trying to get around isn't the authentication. It's the fact that the person AT THE COMPUTER THAT IS BEING CONNECTED TO needs to accept the screen sharing request.
So let's say my wife is logged in downstairs on the iMac but is no longer there. Let's say I'm also logged into that iMac. But I want to do something on her screen.
So from my laptop upstairs, I initiate a screensharing request. I get the window asking if I want to log in OR use the virtual screen sharing. I want to log in to her screen. But then it says it's waiting for her to accept the request downstairs.
It's that step that I'm trying to get around. I have her password, she has mine, etc. If it simply required me to log in AS HER, I could do that. But it keeps insisting on having the user downstairs verify the request, which is a problem because often neither of us is downstairs when I'm making the screensharing request.

I have never seen this need for the person to ACCEPT the request.
Alas, I'm using AppleRemoteDesktop, which might modify the default behavior.
I can't test a bare-bones ScreenSharing.

Have you tried using remote management instead of screensharing in the sharing prefs? My Lion Server doesn't require approval for me to share its screen. It only has one user though and no physical screen.
|
I have plenty of more important things to do, if only I could bring myself to do them....

Remote management rather than screen sharing is the answer. You can still use the screen sharing feature on the machine you are on rather than having to use Apple's full Remote Desktop product.
