Fake Basic Auth

[Christian Felsing]

Hello,

I am new to nginx and have following problem:

Nginx should be used as a reverse proxy and configured for client
certificate authentication. Backoffice application supports basic auth only.
Apache 2.4 solution for that kind of problems is "Fake Basic Auth" so
backoffice application gets a remote_user and password generated from
client certificate presented by user.

Example:
AuthBasicFake %{SSL_CLIENT_S_DN_CN} %{sha1:passphrase-%{SSL_CLIENT_S_DN_CN}}
This set remote user to CN from client certifiate.

is there a similar mechanism in Nginx?

Does HttpLuaModule allow to fake a 401 authentication?

best regards
Christian
