All, I accidentally bumped into this situation and I was wondering if anyone else seen this as well.
When provisioning a LDAP authenticated NiFi instance I defined the initial admin as: CN=BOFH, DC=evil, DC=com To my surprise this did not work. Upon inspection of the authentication and authorization files, I realised that internally NiFi seems to lower case distinguished names "fields" like cn, ou, dc, etc. It happens to be that AD LDS seems to return upper case on all "fields" of the LDAP DN. https://social.technet.microsoft.com/Forums/sharepoint/en-US/d825ec95-94ad-4b0b-93cd-01214c312ef1/returning-lower-case-distinguished-names-from-an-ad-lds-instance?forum=winserverDS Has anyone else noticed that when integrating NiFi into AD? If so, should we raise it as a bug or simply address it via documentation? Cheers
