Consider using --ssl-reqd 21instead to be sure curl upgrades to a secure connection. 22 23Try to use SSL/TLS for the connection - often referred to as STARTTLS or STLS 24because of the involved commands. Reverts to a non-secure connection if the 25server does not support SSL/TLS. See also --ftp-ssl-control and --ssl-reqd for 26different levels of encryption required. 27 28This option is handled in LDAP (added in 7.81.0). It is fully supported by the 29OpenLDAP backend and ignored by the generic ldap backend. 30 31Please note that a server may close the connection if the negotiation does 32not succeed. 33 34This option was formerly known as --ftp-ssl (added in 7.11.0). That option 35name can still be used but might be removed in a future version. 36
