Hi, I'm using SSSD (Kerbeos + LDAP) to authenticate my users. Until 14.04 everything worked perfectly.
Since 14.04 the pam_kwallet module prevents my users from loggin in. lightdm just says "wrong password. please try again".
This is my auth.log:
Apr 27 13:09:41 jan2 lightdm: pam_succeed_
Apr 27 13:09:41 jan2 lightdm: pam_unix(
Apr 27 13:09:41 jan2 lightdm: pam_sss(
Apr 27 13:09:41 jan2 lightdm: pam_kwallet(
and I'm seeing a segfault of lightdm in my syslog (i have attached the crash file):
Apr 27 13:09:41 jan2 kernel: [ 457.034577] lightdm[4104]: segfault at 0 ip 00007facd4548be0 sp 00007fff1c2440b0 error 4 in libc-2.
If I remove pam_kwallet.so from /etc/pam.d/lightdm everything works as expected.
We have just released an update versioned 0.0~git20140410 -0ubuntu2. 1, please verify that you still see this issue with the new version.
