   - The mountpoint is not a sticky directory which isn't owned by the

+When using the `allow_other` option, be aware of
+[bug #15](https://github.com/libfuse/libfuse/issues/15): the
+permission to access a cached directory entry is only checked for the
+first user that accesses it. As long as the directory entry is cached,
+accesses by other users are made with the permissions of the first
+user. The only work around for this bug is to disable caching of
+directory entries, or to not use `allow_other`.
