The long and short of it is you need to make sure that OpenSSH is
using PAM, and that your PAM configuration is correct for doing LDAP
lookups for account info and such.  You also need to modify
/etc/nsswitch.conf.

That is potentially interesting, but there are a wide variety of ftp
servers, and configuring authentication for them varies as well.
Without more details about how your system is configured, I expect it
will be difficult to provide additional useful advice.

Hope that helps.
