------------------------------------
Status: Patch Available (was: In Progress)
> LDAP Authorizer/Login Identity Provider fails when keystore config is empty
> ---------------------------------------------------------------------------
>
> Key: NIFI-14025
> URL: https://issues.apache.org/jira/browse/NIFI-14025
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 2.0.0
> Environment: Red Hat Enterprise Linux 9, Java 21, Microsoft Azure AD
> LDAP.
> Reporter: Isha Lamboo
> Assignee: David Handermann
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> When starting NiFi 2.0.0 with migrated settings that include the LDAP
> authorizer (LDAPS strategy), NiFi failed to start with the error that the
> PKIX pathbuilding failed for the secure LDAP server.
> Keystore and truststore were copied from NiFi 1.28.0 and confirmed working in
> that version. All certificates involved validate correctly with openssl
> verify.
> The configuration in question normally has only truststore details, no
> keystore involved. After finding NIFI-13985, I copied the truststore
> filename, password and type to the keystore entries in authorizers.xml. This
> resulted in NiFi starting correctly, but LDAP login failing. Making the same
> additions to login-identity-providers.xml restored LDAP login as well.
