Ah yes, silly me. You are absolutely <br>
right. It has been such a long <br>
habit... But it does help when people intercept the traffic. Does the <=

ldap plugin send it hashed to the ldap server? <br>
<br>
I think FreeIPA supports salted sha512 but I'm not entirely sure. <br>
<br>
You'll probably say that I need to enable TLS, but there have been many
=
;<br>
weaknesses in ssl and MITM issues. So more is always better in a <br>
security perspective. <br>
