That's an internal method used to escape assertion values. If you run it on the whole filter string it will also escape the other characters that are special in LDAP search filter strings.

eg: Net::LDAP::Filter::_escape("(cn=foo)") returns '\28cn=foo\29'.

That is because "(" and ")" are special characters.

So you can't usefully run it on the entire filter string. You *could* run it on each assertion value you're using, with the caveat that it isn't a public supported method.

Graham, should _escape be made public? It seems like it would be useful. Or is manipulating the data structure returned from new the better approach?
