As far as I know that works out of the box. In order to let tomcat trust
the information, you'd need to set tpomcatAuthentication though.
One unfortunate thing: we use the standard request data REMORE_USER to
forward, and for IIS this is:
"The name of the user as it is derived from the authorization header
sent by the client, before the user name is mapped to a Windows account.
If you have an authentication filter installed on your Web server that
maps incoming users to accounts, use LOGON_USER to view the mapped user
name."
AFAIR this means yo get a lot of different mixtures of upper an dlower
case etc. Not a normalized version of the user id.
When acivating debug log level in mod_jk, there is a line
Service protocol=%s method=%s host=%s addr=%s name=%s port=%d auth=%s
user=%s uri=%s
which contains the authentication protocol ("auth=") and the user name
("user=") being forwarded.
