Terminates the connection if the transfer 21cannot be upgraded to use SSL/TLS. 22 23This option is handled in LDAP (added in 7.81.0). It is fully supported by the 24OpenLDAP backend and rejected by the generic ldap backend if explicit TLS is 25required. 26 27This option is unnecessary if you use a URL scheme that in itself implies 28immediate and implicit use of TLS, like for FTPS, IMAPS, POP3S, SMTPS and 29LDAPS. Such a transfer always fails if the TLS handshake does not work. 30 31This option was formerly known as --ftp-ssl-reqd. 32
