This is an issue for us as well. It seems in our case, the NAS retransmits the
start packet 60 seconds later and this has an impact on the acctuniqueid as
shown in the example below:

As with many companies using load balancing, it may not be good to use
Client-IP-Address to key on as this changed 60 seconds later.
Default in modules/acct_unique:
acct_unique {
key = "User-Name, Acct-Session-Id, NAS-IP-Address, Client-IP-Address, NAS-Port"
}
The man page for rlm_acct_unique shows:
acct_unique {
key = "User-Name, Acct-Session-Id, NAS-IP-Address, NAS-Port"
}
Anyone know when this was changed?

Um yes. Especially if you're using interim updates.
