To automate access to the CUD REST interface a tool is required that will allow authentication using the GSS Negotiate protocol with a Kerberos service principal keytab. The following tools offer this functionality and have been successfully tested to work with the CUD REST interface.
However, these tools are not the only way to access the CUD REST interface, there is no reason why programmatic solutions should not be developed if you have a requirement to.
The curl tool may be used as long as it has been compiled with GSS-Negotiate and SSL support. Compiling with GSS-Negotiate support is dependent upon the availability of particular Kerberos libraries. The MacOS and linux operating systems are examples for which curl has been packaged with built-in GSS-Negotiate support, while curl built for the Windows OS may not have been.
If you see "GSS-Negotiate" and "SSL" in the third line of the output ("Features") you can use curl for this.
If the "GSS-Negotiate" (Negotiate authentication) feature is missing you can alternatively use the java-based command-line tool.
To use this tool you must have installed the prerequisite Java SE (Standard Edition) Runtim Environment (JRE). This is available as a free download from http://java.oracle.com . Alternatively an equivalent OpenJDK edition can be installed if it is available for your OS platform. The minimum required Java Runtime Environment (JRE) version is Java 7.
When the JRE is installed the tool can be invoked as follows:
If a JRE is successfully installed, the output should include an error message, and a usage message
resembling the following:
