Here's the snippet of the login-ceredentials.xml which is present. I have unzipped the file and manually entered the values looking at the existing nifi version:   <!-- This file contains users and their hashed passwords.

@cjervis Many thanks for your prompt response and help for my query. I am a novice when it comes to nifi, so please pardon my silly question.    Upon updating nifi.sensitive.props.key, I am seeing the below message in logs and nifi refuses to start.   Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [java.lang.Object]: Factory method 'loginIdentityProvider' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loginIdentityProviderFactoryBean': FactoryBean threw exception on object creation; nested exception is java.lang.Exception: The specified login identity provider class 'com.batchiq.nifi.authentication.file.FileIdentityProvider' is not known to this nifi. at org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate(SimpleInstantiationStrategy.java:185) at org.springframework.beans.factory.support.ConstructorResolver.instantiate(ConstructorResolver.java:653) ... 53 common frames omitted Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loginIdentityProviderFactoryBean': FactoryBean threw exception on object creation; nested exception is java.lang.Exception: The specified login identity provider class 'com.batchiq.nifi.authentication.file.FileIdentityProvider' is not known to this nifi. at org.springframework.beans.factory.support.FactoryBeanRegistrySupport.doGetObjectFromFactoryBean(FactoryBeanRegistrySupport.java:176) at org.springframework.beans.factory.support.FactoryBeanRegistrySupport.getObjectFromFactoryBean(FactoryBeanRegistrySupport.java:101) at org.springframework.beans.factory.support.AbstractBeanFactory.getObjectForBeanInstance(AbstractBeanFactory.java:1898) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.getObjectForBeanInstance(AbstractAutowireCapableBeanFactory.java:1284) at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:267) at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:208) at org.springframework.context.annotation.ConfigurationClassEnhancer$BeanMethodInterceptor.lambda$createCglibProxyForFactoryBean$1(ConfigurationClassEnhancer.java:540) at org.apache.nifi.web.security.spring.LoginIdentityProviderFactoryBean$$EnhancerBySpringCGLIB$$3e2a6f6e.getObject(<generated>) at org.apache.nifi.web.security.configuration.AuthenticationSecurityConfiguration.loginIdentityProvider(AuthenticationSecurityConfiguration.java:80) at org.apache.nifi.web.security.configuration.AuthenticationSecurityConfiguration$$EnhancerBySpringCGLIB$$218ddc49.CGLIB$loginIdentityProvider$0(<generated>) at org.apache.nifi.web.security.configuration.AuthenticationSecurityConfiguration$$EnhancerBySpringCGLIB$$218ddc49$$FastClassBySpringCGLIB$$b60cd7bc.invoke(<generated>) at org.springframework.cglib.proxy.MethodProxy.invokeSuper(MethodProxy.java:244) at org.springframework.context.annotation.ConfigurationClassEnhancer$BeanMethodInterceptor.intercept(ConfigurationClassEnhancer.java:331) at org.apache.nifi.web.security.configuration.AuthenticationSecurityConfiguration$$EnhancerBySpringCGLIB$$218ddc49.loginIdentityProvider(<generated>) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate(SimpleInstantiationStrategy.java:154) ... 54 common frames omitted Caused by: java.lang.Exception: The specified login identity provider class 'com.batchiq.nifi.authentication.file.FileIdentityProvider' is not known to this nifi. at org.apache.nifi.web.security.spring.LoginIdentityProviderFactoryBean.createLoginIdentityProvider(LoginIdentityProviderFactoryBean.java:169) at org.apache.nifi.web.security.spring.LoginIdentityProviderFactoryBean.getObject(LoginIdentityProviderFactoryBean.java:121) at org.springframework.beans.factory.support.FactoryBeanRegistrySupport.doGetObjectFromFactoryBean(FactoryBeanRegistrySupport.java:169) ... 72 common frames omitted ...
