What's the basis for claiming that there's a corruption problem?  I haven't
seen tdb corruption in samba for many years.

The backtrace in this bug isn't a corruption issue at all; the
get_global_sam_sid() call panics if called by a process that can't create or
read /var/lib/samba/secrets.tdb.  The trick is that libpam-smbpass isn't
supposed to call get_global_sam_sid() - so something has changed here.
