When session locked by kde screensaver, password not recognised

vdemuth · 07-21-2007, 02:23 PM

Hi all,
A quick description of my problem. When the KDE screensaver cuts in, I would like to have the ability to lock the session unless the user password is entered, just as it looks as though it is possible to do fron the Kcontrol centre. Trouble is, although the session gets locked, when inputting the user password, and without exception, the screensaver fails to unlock, with an 'incorrect password' being the reason given. The KDE docs say that the pasword to enter is just the users password, so now I am stuck with my pc not able to be session locked when the screensaver kicks in. As I use this pc in an office, and because this function doesn't seem to work, at the moment I do not have session lock enabled. This is not very secure as you can understand. Anyone any ideas why this happens, and how to put it right.
BTW, normal login for users from KDM works fine, as does console login.

Also tried the suggestion from KDE forum about setting kcheckpassword suid root, but it is still the same. All other suggestions I have found via google recommend using PAM, which PV doesn't include in Slack.

I once had that problem and found out my keyboard settings were not correct when I logged into my desktop, therefore the incorrect characters was being used when I typed my password to unlock my screensaver.

Anyone got any more ideas as the keyboard is set correctly

Is your password made only from latin (ASCII charset) letters? Actually, I don't know if it's possible to include other languages letters in your password, but it's better to make sure.

When you enter kcheckpass into the terminal, does it work for you or not?

Password is only composed of latin characters. Running kcheckpass returns authentication failure. Any idea why this is. As I said, login from KDM is fine, and the password is recognised there and at the cli.

TIA

Does su(-ing) to another user work or not?

Yep, su to root then running kcheckpass works fine, so must be some file somewhere presumably with some permission that needs setting. I have added myself to the shadow group just in case it was as simple as that, but with no luck. Have also changed permissions on the /etc/password and /etc/shadow file, again with the same result. Any more ideas?

OK, a combination of the above, with setting a new password seems to have done the trick.
