Public bug reported:

We use autolog to end idle sessions on systems which are configured with
nss_winbind.  When the DOMAIN\user string is >20 chars this will crash
autolog as a fixed string field is overflowed.  The source seems to have
not had much attention (presumably because it is either typically
reliable or not much used) for a long time.  I have done some work which
resolves the issue that I encountered as well as trying to make it more
reliable by using 'n' variants of sprintf, strcpy etc.  I have published
my modified source at:
