getting computers username

[essjay_d12]

is there a way in which php can grab a computers username,

 

i log into windows as john

 

so i want php to grab john and use that to open up a mysql database with information on the user john.

 

Basically so users do not need to log in themselves twice... ie windows then the website (just windows)

 

as that is enough authentication

 

thanks

Not without some type of activex control, and even then that might be a privacy violation of some type.

No, I don't think there is a way to do that with PHP...how exactly would you know their windows username would be the same as the username they entered in your DB?

 

To keep them logged in, why not just set a cookie?

[essjay_d12]

we know that the username is the same as the database - and we also know it is possible to obtain windows' username through asp

 

so is it not possible in php?

 

cheers

It is only possible for asp without asking the user because internet explorer automatically sends a authorization request with the username to the iis webserver. php probably also can read this value from $_SERVER['PHP_AUTH_USER'] when installed as iis module not as cgi. The manual says

'PHP_AUTH_USER'

    When running under Apache or IIS (ISAPI on PHP 5) as module doing HTTP authentication this variable is set to the username provided by the user.

Most likely not, unsure. ASP probably has that "special" function since it is Microsoft based.

 

<?php
$hostname = gethostbyaddr($_SERVER['REMOTE_ADDR']);

echo $hostname;
?>

 

About the only thing I could come up with but unsure if that works, un-tested.
