Correct. gluster-swift itself is pretty much stateless here
and uses glusterfs for storing all user related data.

You can also choose between two auth systems - tempauth
and gswauth. Tempauth stores usernames and password (plaintext!)
in a conf file at /etc/swift while gswauth uses a dedicated
glusterfs volume to store username and password (hashed).

The ACL information is stored in xattrs regardless of which of
the above two auth mechanisms you choose to use.

gluster-swift has it's configurations files at /etc/swift
and also has ring files there. These ring files determine
which volumes are made available over swift interface.

If you have 10 volumes, you can choose to make only few
of them available over object interface.
