This:

egrep -v '^($|#)' /etc/ldap.conf

matches any line which is not blank and does not have an octothorpe in it. It is not negating a character class which is what you put inside brackets [ ]. It is negating the start of a line or the octothorpe '#'. That leading caret ^ negates each alternative within the parentheses.
