That was ancient code that I did for 4.4BSD and was never adopted by anyone. When people refer to Kerberized NFSv3 these days, they are using the same RPCSEC_GSS code that NFSv4 adopted. This is in Solaris10 and I believe that current versions of Linux2.6 might have the v3 support as well as v4. (As far as I know, the only difference between using RPCSEC_GSS/krb5 on v4 vs v3 is the mount protocol and, at least Solaris10, will allow the mount protocol to use AUTH_SYS for a sec=krb5 mount.) So, if you find a Kerberized NFSv3 it will probably support NFSv4 as well. rick
