On a centos machine ldapsearch was not giving me much love when accessing a Microsoft Global directory server via ldaps and a given port. The error message I got was:


ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)


When turning up debug level via -d 1 as in


ldapsearch -d 1 -v -H ldaps://servername:portnumber


I got the bit more revealing error message:


TLS certificate verification: Error, unable to get local issuer certificate
TLS trace: SSL3 alert write:fatal:unknown CA
TLS trace: SSL_connect:error in SSLv3 read server certificate B
TLS trace: SSL_connect:error in SSLv3 read server certificate B
TLS: can't connect: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed (unable to get local issuer certificate).


It turns out that a simple line like


TLS_REQCERT never


in ldap.conf makes things better. In my particular install a simple ‘locate ldap.conf’ was a bit misleading. The true location of your config file can be revealed via:


strace ldapsearch -v -H ldaps://servername:portnumber 2>&1 | grep ldap.conf


An Apple TV box stopped reacting to the IR when being back in the Apple interface. The light was still changing colors when a button was pressed, but nothing happened. This forum post describes perfectly shows how to get the IR working again. Since it would be a shame if these clear and wonderful instructions would fall prey to data rot here a (slightly amended) copy of them:

1) if you have not already, patchstick the ATV

2) ssh to the atv

(Steps 3 and 4 will fail if you have set the ATV to not auto update its software, since mesu.apple.com will resolve to 127.0.0.1)
3) download the IR firmware update utility: wget http://mesu.apple.com/data/IR/061-3045.20080708.Aq12D/IRReceiverUpdaterTool2

4) download the firmware image: wget http://mesu.apple.com/data/IR/694-5586.20081119.2AvT3/irrxfw-0×0312.irrxfw

(you probably will need to do chmod +x IRReceiverUpdaterTool2)
5) run the firmware patch: ./IRReceiverUpdaterTool2 irrxfw-0×0312.irrxfw

6) if the process worked you should see this message near the end of the output:

Flash Image Verification Succeeded…
SendCmdExitBootLoader
Bootload Success…

At his point the IR indicator blinks yellow. The Apple UI is reacting again. With
an ATV software Version 3.0.2 on a Geforce Go 7300 1GHz ATV the IR became
inoperable after a reboot.

Redoing the update, then unpairing the remote and pairing it again fixed this.

On a side note: I found this blog post 20 minutes after I made it when googling for ‘IRReceiverUpdaterTool2′.

Google is simply amazing.
