Re: ååï mirror mode question

[Dieter KlÃnter <dieter@dkluenter.de>]

Hi,
If I remeber correctly, you mentioned sasl authentication. My comments
on plaintext passwords are only related to sasl authentication. A sasl
authentication is based on a SASL MECHANISM, as described in rfc-4422.
In order to compare the sasl authentication string with the stored
password value, this has to be cleartext.
If your ldap operation is based on a simple bind, the stored password
can, and should be, hashed.
