[Bug 303458] Re: segfault in pam_smbpass.so

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,
