ok thank you I will check. But how to provide access to the Component Toolbar to the users who are not admin? I have overriden that option("which is visible in screenshot from the main question and you also discussed that in your answer above) from admin account and added this user but now that user can only go inside that processor group and things are no longer grey in the processor group but still that user can't bring new processor from the Component Toolbar as whole section is still grey. New Update: So now 5 mins later I went to the admin account again, right clicked on a certain processor-group and clicked on the "Manage Access Policies"-> dropdown which was showing the "View the component"-> changed it to "Modify the component". After this the user is able to bring new processors to that processor group. Is it correct approach? Do I need to provide any more accesses?

Hello I have configured certificate based authorization by using manager-authorizer in nifi.properties and then adding property name ="Initial Admin Identity" in <userGroupProvider> and <accessPolicyProvider> sections of authorizers.xml Now once I do that and import admin cert (which I specified in authorizers.xml) then I can access NiFi and I can bring comonents/processors from Component Toolbar. I can also add users from the Global Menu "Users" section or Add Policies. Issue I am experiencing is that the user I added can only view the processors groups and can't modify them. Apart from this the whole component toolbar is grayed out so not accessible. I went to my admin account and added that user in some Policies but this did not help. I saw in some article that we need to right click on certain processor group and then go to "Manage Access Policies" but surprisingly for my admin account the Add User icon is gray and not able to click it. I have added two photos one showing my user component toolbar being inaccessible and another one my admin cert logged in NiFi where I see Add User icon not accessible.(Note I can add user from Global Menu) How to resolve this? Can someone please advise. I want to provide access to users so that they can do their work in one processor group.

We want to receive the soap request then do some processing and return a soap response. So we are a host or provider for that Soap Api.

Hello I want to know one thing. Let's say we have a flow having a Handlehttprequest then a ExecuteSql processor and then a HandleHttpResponse for example. Daily we receive say 1000 calls to this flow. So where does flowfiles get stored? I see in provenance many many flowfiles. So do they purge or all get accumulated. I have less space so wanted to know.

Hello @MattWho Thank you for a detailed answer. I very much appreciate your time. My requirement is to have say 5 developers are there in my team then I want each to have their own unique userid and password. Currently I have single user setup. You have mentioned LDAP. I am not much aware of it. Is there any helpful article which can help me as a newbie. I again appreciate your much help to this community.

Hello I am confused on one point why are you asking to Remove users.xml and authorizations.xml: rm conf/users.xml conf/authorizations.xml If we remove them then how will changes that we had done in previous steps to the authorizations.xml remain? Also I believe step 1

Hello in NiFi can we have some restriction over users about what can they view and not edit other users processor groups. I want to have like say we have 5 persons then I want to give 5 user id and don't want one to interfere with others work like processor groups and possibly not even view other's processor groups. I was viewing one article (https://docs.cloudera.com/cfm/2.0.4/nifi-admin-guide/topics/nifi-creating-users-groups.html) mentioning "From the UI, select "Users" from the Global Menu." But I am not getting where is this Users option and also Global Menu which icon can be that.

Hello I have a flow where a queue is having say 250 entries but I am able to see only 100. I don't see any option to see the next sets of entries. How to view them as I can see the count to be increasing in queue but it displays oldest 100.
