+Subject: [PATCH] smb: Rework anonymous handling to avoid EINVAL
+
+After the recent samba change, the "Invalid Argument" error can be still
+returned when anonymous login is requested even after the commit 747c7f6.
+This is because `smbc_setOptionNoAutoAnonymousLogin` is called after returning
+from the `auth_callback` function (i.e. there is one redundant iteration).
+Let's rework the handling a bit and call that immediately, which bypasses
+the issue.
+
+Fixes: https://gitlab.gnome.org/GNOME/gvfs/-/issues/619
