Does chain overlay support sasl binding?

[Simon Gao <gao@schrodinger.com>]

Hi,

I'd like to know if chain overlay currently supports sasl binding or not
with OpenLDAP 2.3.35.

Since both idassert-bind and chain-idassert-bind are handled by ldap
backend, can I assume sasl binding should be available to chain overlay
also?

Appreciate your help.

Thanks,

Simon
