Zabbix 1.4.2 with userparemeter problem

[johanpre44]

I can get the userparemeter working with my agent (which is the local host).

I add
UserParameter=sensors.temp.planar,sudo ipmitool sdr|grep "Planar Temp" | awk '{print $4}'
to /etc/zabbix/zabbix_agentd.conf (also restarted the zabbix-agent)

and can test it with "zabbix_agentd -t sensors.temp.planar" which gives me this output: "sensors.temp.planar [t|21]"

But can't get the zabbix server to retrieve this value. The Item I add is this:
Description: Planar Temp
Type: Zabbix Agent
Key: sensors.temp.planar
Type of Info: Text
All the other fields are default.

The Item simply returns "Not Supported", why?

Some more info

I also notice that "zabbix_get -s localhost -p 10050 -k sensors.temp.planar" returns "ZBX_NOTSUPPORTED", and I'm not sure why because I'm pretty sure that I have done everything else right (including restarting the agent).

I know that the other items actually work because "zabbix_get -s localhost -p10050 -k agent.ping" returns "1"
