The iRedMail stock AD integration uses
pass_attrs = userPassword=password
default_pass_scheme = CRYPT
However, while I can query the AD LDAP tree, the userPassword attribute is not available.
Is it possible to authenticate by binding to the AD server, using the client-supplied credentials (if necessary, looking up the proper DN)?
