Hello is there a definitive answer to where to download the JAR files to create beans for the Pre Authentication technique? I've tried the following but there is no preAuth package in the externalAuth package. compile group: 'com.jaspersoft.jasperserver.api.externalAuth', name: 'jasperserver-api-externalAuth', version: '6.3.0' Has the Pre Authentication technique changed with this version? I'm looking at the documentation here: https://community.jaspersoft.com/documentation/jasperreports-server-authentication-cookbook/pre-authentication-option Also, I'm using Jasper Server 6.4.3, is there a place to get JAR files for that version or will 6.3.0 work? Thanks in advance. - Matt
