Answer 1

You can only access the remote user if Apache has actually authenticated the user, check the apache auth howto.

Answer 2

I battled with this for a long time, it turned out that I had to install VC redistributable to make it work.

Answer 3

<Directory "path/to/your/htcdocs/folder"> 
Options None 
AllowOverride All 
Order allow,deny 
Allow from all 
#AuthName "SSPI Protected Place" 
AuthType SSPI 
SSPIAuth On 
SSPIAuthoritative On 
SSPIOfferBasic On 
SSPIOmitDomain On 
Require valid-user 
</Directory>

If you use ModRewrite or other I suggest you to keep

Options Indexes FollowSymLinks Includes ExecCGI

otherwise you'll get an error like

[rewrite:error]: Options FollowSymLinks and SymLinksIfOwnerMatch are both off, so the RewriteRule directive is also forbidden due to its similar ability to circumvent directory restrictions

Answer 4

Finally got it to works! :D

1. Download the module from here https://www.apachehaus.net/modules/mod_authnz_sspi/ (x86 for 32 bit and x64 for 64 bit apache)

2. Copy the mod_authnz_sspi.so from Apache24\modules folder and place it in the modules folder of your Apache folder on your webserver

3. Under the httpd.conf file (Config file for your apache) place this line of code. Try to load this as the last module:

   LoadModule authnz_sspi_module modules/mod_authnz_sspi.so

4. Make sure that the following modules are uncommented

   LoadModule authn_core_module modules/mod_authn_core.so

   LoadModule authz_core_module modules/mod_authz_core.so

   PS: both the above modules are required for this to work.

5. Place the following code in your httpd.conf file

   <Directory "path/to/your/htcdocs/folder"> 
   Options None 
   AllowOverride All 
   Order allow,deny 
   Allow from all 
   #AuthName "SSPI Protected Place" 
   AuthType SSPI 
   SSPIAuth On 
   SSPIAuthoritative On 
   SSPIOfferBasic On 
   SSPIOmitDomain On 
   Require valid-user 
   </Directory>
   

6. Restart your apache servive and hopefully it should restart without any issues.

7. Now in order to recognise the user , use the following code on a php page

   echo $_SERVER['PHP_AUTH_USER'];

That's all.

I'm using:

• XAMPP Control Panel 3.2.1
• APACHE 2.4
