Checking for Unmapped User IDs or Group IDs

To determine whether 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));
}

Note:

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 Oracle Solaris 11.4 DTrace (Dynamic Tracing) Guide.
