Multiple IP Address assigned to same AD User

We are using a Barracuda Web Filter 310 that is communicating to our Domain Controllers for user authentication.  When the Barracuda polls our servers, it is supposedly running a query from DHCP logs.  The problem is that the query is sending over multiple IP addresses that are assigned to the same user and also have seen where an employee was terminated over 6 months ago but they still have an IP address assigned to them in the logs so any new user that gets that IP from our DHCP server is now being tracked/filtered as if they were the terminated employee.  Barracuda said this is a Server2003 issue since their hardware is querying our Domain Controllers.  Is there a way to purge this data on our DC or where in DHCP could we see this information to know what needs cleaned up?  I never knew there was a list of IPs assigned to user accounts.  Or possibly elsewhere on the server other than DHCP?

"Eh?"

Barracuda uses Windows Active Directory Services for Authentication, the user when logged in will use Windows Authentication to authenticate with the Barracuda.

it has nothing (as far as I am aware) to do with DHCP, IP addresses are not assigned to users they are assigned to computers.

Barracuda totally confused me on this.  We do have the DC Agent installed so that it authenticates with Active Directory, but our user list in Barracuda has multiple IPs asssigned to users.  For example, if I log in to multiple computers in the building and use the internet, I will have those IPs show up assigned to me in Barracuda.  If I were to take one of those computers offline for 8 days and let the DHCP lease expire and have the IP reassigned to another computer, the person surfing the net will still show up as myself in the web logs?  How does an IP address get linked to a username?  I agree that the IPs are assigned to computers.  I'm lost on this one.
