I have a private computer that is mine, with a passworded account. But occassionally our family computer breaks and the family want to to use mine. I have created an account "guest" and would like to be able to tell them to use that (passwordlessly) - particularly when I am away on business. -- Alan Chandler [EMAIL PROTECTED] First they ignore you, then they laugh at you, then they fight you, then you win. --Gandhi

If I have a Linux desktop machine at home, and I give the kids an account and one for myself, I want (and need) a password on my account, I don't have any security purpose to putting passwords on their account. In fact, allowing them a password at all is just giving them a false sense of security :-)

There's a rather huge difference: the graphical shell is still unlocked without a password, but people can't just use that account and login e.g. via ssh without a password. Huuge difference.

Re: [FAQ] Passwordless logins don't work in KDM 3.2
It does work? Hmm, if so, then it matters little to me which one is used. If I might ask, what's the difference, from KDM's point of view, as the user isn't prompted for a password in either scenario, effectively making either one a passwordless login...

What? That is utterly irrelevant. It is her and her machine only. She lives with her elderly husband, and I dont think they can even work KMail properly, let alone Kazaa. Anyway, my policy is that access to that machine is limited at the PHYSICAL level, and I have decided it is sufficient. I fail to see why it's anybody else's right to question this, although I do see the point you're trying to make here. All I am saying is, that it is my decision to make whether to do it this way, not anybody elses, hence I will be most peeved if the decision is denied me, through its removal from kdm. > > > Secondly, I maintain a machine in the university PC labs for public CD > > burning of linux distros.

Oh, so the X11 app I wrote isn't good enough? We dont mind people opening terminals anyway, and the machine is effectively open access, so again, this doesn't matter. Non-root access to this machine is not cared about - at least, again, it is managed PHYSICALLY - not just anybody can get into our labs. If you were to come in, and ssh out from it, I don't care. Likewise, if you download a kazaa client, I dont care, although if I spot it, I WILL kill it ;) > > Thirdly, as kdm already does support it (excluding this minor regression, > > obviously!) why remove it?

Absolutely - there are a number of scenarios where this behaviour is almost mandatory - I have two. Firstly, my mother's PC - she is the only person who ever used it, and can even access it, so why can't I allow her to autologin? It's one less thing for her to worry about. Secondly, I maintain a machine in the university PC labs for public CD burning of linux distros. I autologin it as guest user, and spawn the app. Now, if I couldn't use kdm to do it, I'd have to resort to another hack, which is potentially even worse :/ Thirdly, as kdm already does support it (excluding this minor regression, obviously!) why remove it?
