It was 3.0.14. I've just installed 3.0.20b.

We aren't seeing this at any other customers' sites, but most are using 
security = domain against W2k or W2k3. The others are probably running as 
a PDC.

I'm using NetBSD, but pkgsrc is lagging a bit. Both the releases have been 
based on pkgsrc, but manually upgraded to the latest version. The source 
is from ftp://ftp.samba.org/pub/samba/old-versions/
