[squid-users] Weird username?

Hey all,

  Using NTLM auth. I just set up sarg and noticed weird usernames.
So, I looked in my squid log, in case they were being parsed weird and I
see this:

1145472531.457 0 127.0.0.1 TCP_CLIENT_REFRESH_MISS/200 4569 GET
http://server44/squid-reports/ TlRMTVNTUAACAAAAB

That looks like NTLM garbage.. Can anyone confirm what is in my log
file, and if it's expected?
