LDAP is not affected - it requires the user to enter a password. Same
would be for any PAM plugins that actually require the user to enter a
password, I think.

Kerberos is not affected either, because the server does not get a copy
of the ticket. In theory it could be affected if the server requested a
delegation enabled ticket, and exported it so it could be used, but none
of these are done.
