I don't see any issues with this proposal. The interoperatbility with CIFS clients and AD is what I'd expect. The keytab entries for Solaris are again what I'd expect (I wasn't aware of the need for the netbios one though).
So I'm happy to give this a +1 as specified. The one nit I have is I didn't see an updated smbadm(1M) man page - is that because there are no visible interface changes to it ? -- Darren J Moffat
