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.
