Thanks; that certainly narrows it down. It could be that you’ve uncovered a bug 
with the LdapIdentityProvider when using START_TLS. I’ll try to recreate it and 
dig into it on my end. Thanks for sharing all this info.

I was able to remove the TLS information in the identity-provider.xml and was 
able to use my remote LDAP to login. So I think I am narrowing down the issue.

Thanks Scott,


I don’t see anything wrong with your configuration. I created a free jumpcloud 
account, so I’ll try to recreate this issue and get back to you if I have any 
other insights.

Subject: Re: Nifi Registry LDAP


I was able to switch back to my local LDAP server and was able to login 
successfully. The provider I am using in identity-providers.xml is as follows:





        <property name="Authentication Strategy">SIMPLE</property>


        <property name="Manager DN">cn=Manager,dc={redacted},dc=com</property>

        <property name="Manager Password">{redacted}</property>



        <property name="Referral Strategy">FOLLOW</property>

        <property name="Connect Timeout">10 secs</property>

        <property name="Read Timeout">10 secs</property>


        <property name="Url">ldap://{redacted}:389</property>

        <property name="User Search 

        <property name="User Search Filter">uid={0}</property>


        <property name="Identity Strategy">USE_DN</property>

        <property name="Authentication Expiration">12 hours</property>



This is a super strange issue as to why nifi works with the remote LDAP and 
nifi-registry does not.

Thanks Kevin for sending that back,


This is what I see when looking at the Headers on the login.

The version of Nifi-Registry I am running is 0.1.0. What confuses me is that 
this was working with my local LDAP fine. It just stopped working when I 
switched to setting up the identity-provider.xml with the same credentials as 
my nifi-cluster.

If everything is configured correctly, this error usually indicates that the 
server did not locate your login credentials when processing the login request. 
That usually means it will not even attempt to authenticate the credentials, so 
I'm not sure it is an LDAP configuration error.


If you want to check this manually using developer tools in a browser (e.g., 
Chrome or Firefox) you can look at the HTTP traffic to see if credentials are 
being passed to the server. NiFi Registry uses the HTTP Basic Auth protocol to 
login (credentials are encoded in the Authorization header and passed to the 
server from the login page to generate a temporary authentication token). 


So after clicking "Login", you should look for an HTTP POST to 
<base_url>/nifi-registry-api/access/token/login, which should have an 
"Authorization" header with the value "Basic {encoded-username-and-password}"


If the credentials are there, it is likely something is misconfigured on the 
server side with the identity provider so that login credentials are not even 
being looked for. If the credentials are not there... well I've never seen 
that. I would probably as if your NiFi Registry Server running behind a load 
balancer or proxy that could be interfering with HTTP headers?


What version of NiFi Registry are you using? 0.1.0 or a version built from 


Hope this helps,
