I have completed the ldap set up for Nifi. After restarting I am able to authenticate with the initial admin but rather than being directed to the canvas, I am taking back to the /nifi/login page. The page says "Success" with a logout and home link and a message below that says "You are already logged in". Clicking the Home link takes me back to the same page. After enabling debugging here is the messages I see in the nifi-users.log file: 2018-01-25 15:50:56,006 DEBUG [NiFi Web Server-20] o.a.n.w.s.NiFiAuthenticationFilter Checking secure context token: null 2018-01-25 15:50:56,007 DEBUG [NiFi Web Server-20] o.a.n.w.s.x509.X509CertificateExtractor No client certificate found in request. 2018-01-25 15:50:56,007 DEBUG [NiFi Web Server-20] o.a.n.w.s.NiFiAuthenticationFilter Checking secure context token: null 2018-01-25 15:50:56,007 INFO [NiFi Web Server-20] o.a.n.w.s.NiFiAuthenticationFilter Attempting request for (eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJjbj1lNzgzMTV0LG91PVVzZXJzLG91PUFjY291bnRzLGRjPWludGVybmFsLGRjPXNsbWJhbmssZGM9bmV0IiwiaXNzIjoiTGRhcFByb3ZpZGVyIiwiYXVkIjoiTGRhcFByb3ZpZGVyIiwicHJlZmVycmVkX3VzZXJuYW1lIjoiZTc4MzE1dCIsImtpZCI6NCwiZXhwIjoxNTE2OTU2NjU0LCJpYXQiOjE1MTY5MTM0NTR9.a8f8h-Jv2_2qo-0kr9KTCTGFKW3SMeuN772RcUPLZLM) GET https://s617985dc2vl485.internal.redacted.net:9091/nifi-api/flow/current-user (source ip: 10.0.108.100) 2018-01-25 15:50:56,010 INFO [NiFi Web Server-20] o.a.n.w.s.NiFiAuthenticationFilter Authentication success for cn=e78315t,ou=Users,ou=Accounts,dc=internal,dc=redacted,dc=net 2018-01-25 15:50:56,013 DEBUG [NiFi Web Server-20] o.a.n.w.s.NiFiAuthenticationFilter Checking secure context token: cn=e78315t,ou=Users,ou=Accounts,dc=internal,dc=redacted,dc=net 2018-01-25 15:50:56,013 DEBUG [NiFi Web Server-20] o.a.n.w.s.a.NiFiAnonymousUserFilter SecurityContextHolder not populated with anonymous token, as it already contained: 'cn=e78315t,ou=Users,ou=Accounts,dc=internal,dc=redacted,dc=net' 2018-01-25 15:50:56,138 DEBUG [NiFi Web Server-21] o.a.n.w.s.NiFiAuthenticationFilter Checking secure context token: null 2018-01-25 15:50:56,138 DEBUG [NiFi Web Server-21] o.a.n.w.s.x509.X509CertificateExtractor No client certificate found in request. 2018-01-25 15:50:56,138 DEBUG [NiFi Web Server-21] o.a.n.w.s.NiFiAuthenticationFilter Checking secure context token: null 2018-01-25 15:50:56,138 DEBUG [NiFi Web Server-21] o.a.n.w.s.NiFiAuthenticationFilter Checking secure context token: null 2018-01-25 15:50:56,139 DEBUG [NiFi Web Server-21] o.a.n.w.s.a.NiFiAnonymousUserFilter Populated SecurityContextHolder with anonymous token: 'anonymous' 2018-01-25 15:50:56,141 INFO [NiFi Web Server-21] o.a.n.w.a.c.AccessDeniedExceptionMapper anonymous does not have permission to access the requested resource.
