Hi there,

Not that this is much of a problem, more a curiosity, but whenever I put my computer to sleep at night, it forgets any and all passwords it should know.

An example:

I put my computer to sleep, go to sleep myself, wake up, go to work, come back, wake my computer and notice I can't connect to the Internet. No biggie, I just change the Network settings. But I can't because the settings are locked and I need to authenticate myself.

In the subsequent dialogue where you usually see your name displayed, I get nothing. Typing in my username/password results in an 'authentication denied' message.

So I log out, and try to log in as root (I have root access enabled simply because I am root on 12 50.000 dollar machines at work, and so I'm gonna be root on my single 5.000 dollar machine at home), but no dice: screen shakies are the result. In fact, I can't log in as any of the users.

After a restart, all is well again.

Now, as I said, it's no big problem because I put my computer through a rigorous sleep-deprivation regime, but it's an interesting phenomenon.

My main questions are:
1] Anybody know what process takes care of the authentication mechanism and how the communication goes from input to that process?
2] Where are passwords kept?
3] Anyone notice a similar problem?

Any ideas/mindless banter appreciated.

Oh yeah, as for my system: a completely stock G4 DP 500, 256MB RAM, 40GB HD (partitioned in OS 9 and OS X part), 100MB Zip disk (built-in) and DVD-RAM drive.

I had the same effect. It might be connected to my problems with login/logout long delays. Since the request for user permissions is passed to netinfo/lookupd by the login app, which searches the remote and local domains for that info, the problem can get a hassel.
Since I changed the search order of lookup to first look for local services, rather than remote services, everything is better. Also the password weardness I had is gone now.

I suspect, that after deep sleep, lookupd performs a new initialize process and queries users and permissions again, but looks at networked services first, and subsequently times out then without looking locally and therefore loosing the info about user/permission/password.

After a cold boot it regains that knowledge because it queries local info by default then.

Just a guess.

The tip for the altered search order has been provided by a macnn poster, do a search for "login delay", if interested in the particulars.
