Re: PHP - authenticate and authorize using AS400 profile

[Scott Klement <web400@xxxxxxxxxxxxxxxx>]

UserID %%CLIENT%% doesn't work with Zend Core because the PHP is 
actually running in a separate instance of Apache that runs in PASE.  So 
the UserID directive in the native Apache has no effect.

You could code the UserID directive in the PASE instance, but can't use 
the value %%CLIENT%% because it's compiled for AIX and it doesn't 
understand IBM i user profiles and passwords.

You *can* use PasswdFile %%SYSTEM%% on the proxy, and provided that the 
PASE instance is only bound to localhost, that will force a valid 
userid/password before the PHP script is invoked.  But it won't run with 
the user's authority, it'll still run as "NOBODY".

However, in the PHP script you could do this:

$conn = i5_connect( $_SERVER['HTTP_X_FORWARDED_SERVER'],
                    strtoupper($_SERVER['PHP_AUTH_USER']),
                    $_SERVER['PHP_AUTH_PW']);

At least then, any i5_xxx routines will run under the appropriate 
user/password.
