LDAP: Domino v8

WAS: version 6

is it possible to implement filter in WAS v6 like in version v6.1.

For example, I want to configure WAS security in next way:

to enable only users who belong to the companyName "company" under o=organization of the corporate LDAP to have access to Portal.

I know have I can do this in WAS v6.1 but I not sure is it possible in prior versions.
