Httpd has no permission to access /var/lib/gssproxy/default.sock

The directory /var/lib/gssproxy is listed in StateDirectory, and the permission will be changed to 0700 after starting gssproxy.service because of StateDirectoryMode=0700. Httpd's children run by user apache, they can't access /var/lib/gssproxy/default.sock.
