When you try to pass authorization headers via PHP to provide a login interface, you’ll notice it doesn’t work when running it with FastCGI enabled in Plesk by default. It does work with the standard mod_php Apache module for PHP.
The solution is to add the following directive to your Apache configuration in Plesk. Add this to the /var/www/vhosts/[DOMAIN]/conf/vhost.conf file.
FcgidPassHeader Authorization
And run the Plesk Reconfigurator so it knows to include that vhost.conf file in the Apache configs.
# /usr/local/psa/admin/bin/websrvmng -av
Test your config:
# service httpd configtest
Syntax error on line 7 of /var/www/vhosts/[DOMAIN]/conf/vhost.conf:
Invalid command ‘FcgidPassHeader’, perhaps misspelled or defined by a module not included in the server configuration
But that doesn’t work. That’s because Plesk starts with its own implementation of the FastCGI and not the “normal” one.
rpm -qa | grep ‘fcgid’#
psa-mod_fcgid-1.10-3
The solution is as simple as installing the regular mod_fcgid to replace it.
# yum install mod_fcgid
And your list should look similar to this.
# rpm -qa | grep fcgid
psa-mod_fcgid-1.10-3
mod_fcgid-2.3.5-2.el5.art
And the configtest will now work.
# service httpd configtest
Syntax OK
The extra FastCGI parameter is now being included as it should and will pass along the Authorization headers via PHP.
