 Example:

+The test accepts NetWare-style `VOL:PATH` arguments.  It logs in through
+libncp, allocates a temporary directory handle for the volume root, and sends
+only the relative path to `AFP Get Entry ID From Path Name`, matching the
+WebSDK request layout of `DirectoryHandle + Path String`.
+
+Useful smoke cases for a standard MARS-NWE `SYS` volume are:
+
+```sh
+./tests/linux/afp_entry_id_smoke -S MARS -U SUPERVISOR -P secret SYS:
+./tests/linux/afp_entry_id_smoke -S MARS -U SUPERVISOR -P secret SYS:PUBLIC
+./tests/linux/afp_entry_id_smoke -S MARS -U SUPERVISOR -P secret SYS:SYSTEM
+./tests/linux/afp_entry_id_smoke -S MARS -U SUPERVISOR -P secret SYS:BURST
+```
+
+A successful reply prints the temporary directory handle, the relative request
+path, and the returned 32-bit AFP Entry ID.  Server-side diagnostics currently
+mark stat-derived temporary IDs with `fallback`; that means the endpoint is
+reachable, but persistent CNID/AppleDouble entry-id storage is still future
+Mac-namespace work.
+
 If the server was built without the optional Netatalk/libatalk backend, the
 endpoint is expected to return invalid namespace.  To treat that as a successful
 negative smoke test, use:
 
 ```sh
-./tests/linux/afp_entry_id_smoke --allow-invalid-namespace -S MARS SYS:LOGIN
+./tests/linux/afp_entry_id_smoke --allow-invalid-namespace -S MARS -U SUPERVISOR -P secret SYS:PUBLIC
 ```
+
+For path-resolution negative tests, use `--allow-invalid-path` to accept the
+expected `0x9c` Invalid Path completion.
