Mainly it's used in the legacy LM authentication. See
http://davenport.sourceforge.net/ntlm.html for details here.
For Kerberos it's a configuration issue.

At least S3 does not do Kerberos itself, we delegate this to the system
libraries. If you allow DES is a matter of configuration, but normally,
we do not do DES for Kerberos.
