There are a fair number of ber calls which do not check for
errors: Just ber_scanf and use the expected output variable,
which may or may not have a useful NULL value on error.

Syncrepl is particularly bad.  This in slapd/ and libldap/:
  egrep '^<tab>*ber_(scanf|get_)' *.c */*.c
returns mostly syncrepl matches.  I can't even fix these
easily because there's not enough error handling code to
copy.

grepping for ber_(printf|put_) find other modules as well.
