What does NFS getattr failed/RPC: Authentication error mean?
You are probably running a pre-4.0 version of NFS and your username is in more than 8 groups. There is a limit on the number of groups that could be represented in the rpc service (called NGRPS). On pre-4.0 systems this was 8, now it is 16. Since many vendors other than Sun are still running old versions of NFS, you might see this error even if your SunOS is recent. Authentication errors are also caused by having secure RPC enabled on the client but not on the server, or by having a misconfigured secure RPC configuration for the user name generating the errors. Beware of this problem when you are using the automounter, as programs (such as Sendmail) may silently fail when when they try to mount a directory and get this error.
