I have a problem with Ubuntu 12.04 when I trying to integrate with Active Directory.

I installed CentrifyDC and i joind the DC. Everything is ok until I reboot my computer and when I try to login with username and domain password I can't do it.Then I log in with my default ubuntu username and if i try command adinfo appears centrifydc in diconnectd mode. After 3 minutes without any interventions when I type adinfo command centryfidc appears connected and I can login with my domain user and pass.

Same thing is if I execute command: /etc/init.d/centrifydc restart it appear connected.

Can anyone tell me why it can't connect at the boot ? Error when I type: adinfo --diag is: Cannot find SPNs: unable to bind to DC.

Finally, problem resolved by making a script in /etc/network/if-up.d/

sudo vim /etc/network/if-up.d/centrify

with content:

    #!/bin/sh

if [ "$IFACE" = lo ]; then
        exit 0 
fi

/etc/init.d/centrifydc restart
initctl emit centrify-connected

after I typed:

sudo chown root /etc/network/if-up.d/centrify
sudo chgrp root /etc/network/if-up.d/centrify
sudo chmod 755 /etc/network/if-up.d/centrify

And then I modified /etc/init/lightdm.conf with right permissions (chown root, chgrp root, chmod 644), and I added only one boot condition.

sudo chown root /etc/init/lightdm.conf 
sudo chgrp root /etc/init/lightdm.conf 
sudo chmod 644 /etc/init/lightdm.conf 

then

sudo vim /etc/init/lightdm.conf 

and I added only one boot condition.

    if [ "$RUNLEVEL" = S -o "$RUNLEVEL" = 1 ]

        # Single-user mode
        plymouth quit || :
        exit 0
    fi
    fi

    exec lightdm
end script

post-stop script
    if [ "$UPSTART_STOP_EVENTS" = runlevel ]; then
        initctl emit desktop-shutdown
    fi
end script

Be very careful when you do this !
