Description Holly 2008-12-11 01:19:05 UTC

Version:            (using Devel)
OS:                Linux
Installed from:    Compiled sources

When the screen is locked, attempting to unlock it with the proper password fails, giving an "Unlocking failed" error, or something to that effect. It basically acts like my password is wrong, even though it isn't.

My password has a capital letter and numbers in it, if that helps.

is kcheckpass setuid root?

Comment 2 Holly 2008-12-11 04:29:06 UTC

By kcheckpass I assume you mean the three files with that name. I searched for em and yup, they are all owned by root.

Comment 3 Oswald Buddenhagen 2008-12-11 12:16:51 UTC

foo@bar > cd $prefix/lib/kde4/libexec; ls -l kcheckpass
-rwsr-xr-x 2 root root 246059 Aug 21 13:36 kcheckpass
   ^
 *that*

assuming it is, check the authpriv.* syslog facility.

oh, you could just run kcheckpass on the command line and tell us the result.

It doesnt work for me either. Running the nightly build for kde 4.2 on my Ubuntu 8.10 installation.

-rwxr-xr-x 1 root root 13772 2008-12-09 21:35 /opt/kde-nightly/lib/kde4/libexec/kcheckpass

running it says authentication failure with my password.

my auth.log has the following entry
Dec 11 07:51:04 abc-laptop kcheckpass[30474]: Authentication failure for abc (invoked by uid 1000)

Comment 5 Arun Mallikarjunan 2008-12-11 14:05:22 UTC

I fixed mine by doing
sudo chmod u+s /opt/kde-nightly/lib/kde4/libexec/kcheckpass

Dont know why it wasnt that way in the first place.

Comment 6 Holly 2008-12-11 16:46:08 UTC

Yeah, running that command fixed it for me, too. Thanks!

Comment 7 Oswald Buddenhagen 2008-12-12 01:37:53 UTC
