Hi gang, I've been using Samba for years now. Its great, but lately I've become aware of the security issues it presents. Currently I have a setup that uses the securtiy = domain style authentication. Basically a W2K server is used for as the PDC. But after applying the recent RPC denial of service patch to my 2K server, my sambas can no longer use my 2K server to authenticate. I'm afraid that this patch has tightened security over RPC specifically IPC$ to the point were samba is unable to auth against it ( this is backed up by what I've seen from debugging level boosted up ). At this point, I would like to hear from people that confirm a similar problem, before giving out more details, and what I've come up with so far. Thx, CpC
