The error means the running user of netprobe has no rights to query the AD/LDAP for the group info they belong. In that case, it should be related to a local account rather than a domain account. Even so, "Success(0)" means no error was returned for the query request, but the query was successful, but no response was obtained.

By default, Linux is designed to only have root as admin (userid 0 and group id 0) and the other users to be sudoers (elevated rights), If more than one user is assigned to group 0, then Linux Process Context will return no group info can be extracted. Security enhancement software normally modifies the groups so that only specific users or groups can obtain information.

The error in the grand scheme of things is harmless, it will not impact monitoring.
