```
+    lbeentry.st_auth_method = MyClientConnectionInfo.auth_method;
+    if (MyClientConnectionInfo.authn_id)
+        strlcpy(lbeentry.st_auth_identity,
MyClientConnectionInfo.authn_id, NAMEDATALEN);
+    else
+        MemSet(&lbeentry.st_auth_identity, 0,
sizeof(lbeentry.st_auth_identity));
```

I believe using sizeof(lbeentry.st_auth_identity) instead of
NAMEDATALEN is generally considered a better practice.

Calling MemSet for a CString seems to be an overkill. I suggest
setting lbeentry.st_auth_identity[0] to zero.

Except for these nitpicks v4 LGTM.
