[rancid] rejoin AD

[Linux Threads]

Hi Freeradius Users,

I was hoping you can help me in the right direction, after following
http://deployingradius.com/documents/configuration/active_directory.html
all is working fine however I have to join the domain repeatedly

sudo /usr/bin/net join -U NETWORK-SERVICES%mypassword

is there a way to check that the domain membership discontinued and
then rejoin? I am running the above in cron hourly I am sure there is
a better way

Regards

Juan
