I have a PHP script handling authentication for pure-authd, and the problem is that it fails. After a reboot it is still failing. If I log in, restart it manually and monitor the log files, it works. As soon as I log out it fails!
I’ve come to the conclusion that pure-authd doesn’t properly daemonize, and detach from the controlling terminal. PHP was actually using fsockopen to another server and it stopped being able to use DNS because I logged out of the shell.
I ended up switching to the IP of the server. While this is not the ideal solution, it works because internally the IP is a reserved DHCP address for the server, and we shouldn’t be updating the server any time soon.
