Ok here is my issue, I have compiled and installed the latest stable version of squid and samba, and all seemed well until I tried the following command and got the following output. Anyone have any idea why this is not working like it used to, on my other box it will give the prompt where I can enter my username and password and it returns ok. Wbinfo -u and -g will populate the user and group info so I am pretty sure that is setup correctly, I just seem to be missing something here .
