RE: [PHP] PHP LDAP - Single Sign On

[snip] thanks for the response, i can see how this works (i think) for basic authentication with user input,but what i really need is to actually retrieve the logged on user name after a user has logged into windows. i.e. the user name that the http client passes to the apache mod has been captured not from user input, but from say a piece of code that picks up the user name when the user logs in. Probably less to do with php now that i come to think of it, but thanks anyway. [/snip] Ah...I see now. Several have asked this question, let me rephrase and see if this makes better sense.... How can one capture the login user name from a Windows logon? ASP can do it, but can it be done with PHP as one would do with PHP_AUTH_USER? IIRC I don't think that it is possible with PHP.
