Apache LOGON_USER to pass Natural RPC on BS2000

Hello everyone.

I have a problem, any help will be welcome.

In an environment with BS2000, Apache, Natural Web and Windows need to catch the LOGON_USER variable on the web server in order to pass it to RPC, I have put the line ENV = LOGON_USER in nww3cgi.ini but does not appear in the list of environment variables with NAT-ENV.
I enabled the modules uthnz_ldap_module and ldap_module in the file http.conf but still the same.

I would appreciate any input that allows me to solve my problem.
