Upgrading Squid - winbind issue

[Mike Diggins <diggins@xxxxxxxxxxx>]

I'm upgrading Squid from 2.5Stable14 to 2.6Stable20, and Samba from 
3.0.14a to 3.0.30. I'm also upgrading the OS from Solaris 8 to 10. We use 
winbind to authenticate Squid users to a Windows domain.

As per the squid/samba instructions, I've run the command 
'/usr/local/samba/bin/net rpc -S as7 changetrustpw' daily in a cron job. 
I'm not really sure it's necessary, but it has never caused a problem. 
However, on the new server, when I run this command it breaks my trust 
with the domain controller.

Does anyone know why it might be behaving differently? Is running this 
command even necessary?
