OK, all three now report correctly.
So for anyone who may have implemented any of the masq custom-templating for pam_auth or ncsa_auth the reporting of your accesses will be different than before once the new versions of squid, sarg, dans are installed. My own alterations cause the problem. Once I removed custom templates for masq, commented the user_ip out (as is default in the rpm) and set the db for sarg logfile to squid- reports include the userid as I wanted.
