Checking for Unmapped User or Group IDs

To determine if any user or group cannot be mapped on the server or client, use the following script:

#! /usr/sbin/dtrace -Fs

sdt:::nfs4-acl-nobody
{
     printf("validate_idmapping: (%s) in the ACL could not be mapped!", 
stringof(arg0));
}

The probe name that is used in this script is an interface that could change in the future. For more information, see Stability Levels in Solaris Dynamic Tracing Guide.
