In servers/slapd/sasl.c, the check at the beginning of slap_auxprop_init() (that
out_version and plug are not NULL) uses the bitwise "or" when the logical "or"
is what's likely intended.

This doesn't appear to have any impact (both out_version and plug are logically
inverted before this, so the values being used are either 0 or 1), but it might
be better if it were changed anyway.
