CURLOPT_KRB4LEVEL
Constant
CURLOPT_KRB4LEVEL is one of the accepted parameters for curl_setopt parameter #2.
CURLOPT_KRB4LEVEL — The KRB4 (Kerberos 4) security level. Any of the following values
(in order from least to most powerful) are valid:
"clear",
"safe",
"confidential",
"private"..
If the string does not match one of these,
"private" is used. Setting this option to null
will disable KRB4 security. Currently KRB4 security only works
with FTP transactions.
