Consider using --ssl-reqd 21 instead to be sure curl upgrades to a secure connection. 22 23 Try to use SSL/TLS for the connection - often referred to as STARTTLS or STLS 24 because of the involved commands. Reverts to a non-secure connection if the 25 server does not support SSL/TLS. See also --ftp-ssl-control and --ssl-reqd for 26 different levels of encryption required. 27 28 This option is handled in LDAP (added in 7.81.0). It is fully supported by the 29 OpenLDAP backend and ignored by the generic ldap backend. 30 31 Please note that a server may close the connection if the negotiation does 32 not succeed. 33 34 This option was formerly known as --ftp-ssl (added in 7.11.0). That option 35 name can still be used but might be removed in a future version.
