Issue/Introduction

After upgrading to DX NetOps Spectrum  21.2.9 or later,  REST API PUT isn't working. 

Environment

DX NetOps 21.2.9 and later

Cause

REST authentication was changed from BASIC to FORM

Resolution

Needed to change the FORM based authentication back to BASIC in the context.xml by changing the class name value:

• Open the file $SPECROOT\tomcat\conf\context.xml file.
• Change the className value to className="org.apache.catalina.authenticator.BasicAuthenticator".

Then change the authentication in the web.xml:

• Open the file $SPECROOT\tomcat\webapps\spectrum\WEB-INF\web.xml file.
• Replace <auth-method>FORM</auth-method> with <auth-method>BASIC</auth-method>.
• Restart Tomcat.
