[Dx-packages] [Bug 1314095] Re: Unity Lockscreen in 14.04 can't unlock when using LDAP account
Hello Jan, Apparently the LTSP authentication method for the client is not the same as for the server, I was to hastly to say that sssd was installed in the LTSP client like it is on the server, it is not by default. There are no errors unix_chkpwd in the logs but: Jul 9 08:44:58 zotac-44 compiz: PAM unable to dlopen(pam_kwallet.so): /lib/security/pam_kwallet.so: cannot open shared object file: No such file or directory Jul 9 08:44:58 zotac-44 compiz: PAM adding faulty module: pam_kwallet.so Jul 9 08:44:58 zotac-44 compiz: pam_succeed_if(lightdm:auth): requirement user ingroup nopasswdlogin not met by user testuser Jul 9 08:45:12 zotac-44 unix_chkpwd[4847]: password check failed for user (testuser) Jul 9 08:45:12 zotac-44 compiz: pam_unix(lightdm:auth): authentication failure; logname= uid=2683 euid=2683 tty= ruser= rhost= user=testuser Jul 9 08:45:14 zotac-44 compiz: PAM unable to dlopen(pam_kwallet.so): /lib/security/pam_kwallet.so: cannot open shared object file: No such file or directory Jul 9 08:45:14 zotac-44 compiz: PAM adding faulty module: pam_kwallet.so Jul 9 08:45:14 zotac-44 compiz: pam_succeed_if(lightdm:auth): requirement user ingroup nopasswdlogin not met by user testuser -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

I have this behaviour on an LTSP client (ubuntu 14.04), chmod u+s /sbin/unix_chkpwd does not appear resolve it and I am using sssd to authenticate to ldap The screen-lock doesn't work by default in LTSP, I had to activate it with unity-tweak-tool. But it is useless since unlock doesn't work. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.
