Still struggling to reproduce this. There seems to be something CUPS-related that results in secrets.tdb corruption with "Unable to open tdb '/var/lib/samba/group_mapping.ldb'" error messages. Once corrupted, this file seems to trigger libpam- smbpass segfaults.
Following the error message lead, it might come from CUPS apparmor profile, preventing access to LDB. Bug 217787 created an abstractions/smbpass that is noticeably missing /var/lib/samba/*.ldb files: /var/lib/samba/*.tdb rwk, -- segfault in pam_smbpass.so https://bugs.launchpad.net/bugs/303458 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
