Just checked thru both the RTCW and ET code for the fix, and may have found the problem. The fix is a two part fix (code that needs adjusted in 2 diff places), in the ET version, I forgot to add the second part of the fix.
So, if vlvttv has it set on his server, it would eventually start to get used.
I've fixed the bug now, it will be in the next patch.
In the meantime, everyone will have to set "sv_privateClients" to 0, and "sv_privatePassword" to nothing.
