Duplicate accounting log entries

Hope someone can help, as this has me banging my head on the wall :]
I am getting duplicate updates from my NAS, and Im trying to figure out
how to prevent them from being written to my accounting logs table.
I unfortunately have absolutely no control over the NAS, so thats not
even an option.
What I want to do is make the acct_session_id or acct_unique_id fields
unique, or even make a composite key of them both, but I have found
entries in my table where the following happens:
This scenario is with DSL accounts:
I have 3 records for 3 different users all with the same
acct_session_id. 2 of these records have the same acct_unique_id, and
the 3rd has a different acct_unique_id. Everything else in the records
If I make a composite key combining the session and unique id's I will
get rid 1 of the 2 records that have the same unique id, but I will
still be sitting with 2 duplicate entries, each with a different unique id.
I then thought to make the acct_session_id unique, which would solve the
above scenario, but then I came across another problem.
This scenario deals with dialup accounts:
I have 2 records with the same acct_session_id but they are for 2
different users. Each record has a different acct_unique_id though. So
if I make a composite key combining the session and unique id's both
these records will exist, which is correct as they are for 2 different
users. If I make only the acct_session_id unique to solve the DSL
problem above, then one of these records wont be inserted, and an update
will occur instead, as per the alternate accounting query.
Am I missing something? Is there any other way to do this? I do not know
why I am getting duplicate acct_session_id's from my NAS, but as I said
there is no way for me to go that route...
Any help or guidance would REALLY be appreciated!
