Good evening. I have recently migrated my nifi service host server from local resolution of users and groups to use an LDAP server. I configured login-identity-providers.xml and nifi.security.user.login.identity.provider. I verified my configuration is known to NiFi by first restarting my nifi service and then attempting a login to the URL by a user without a cert, forcing it to resolve using LDAP. This appeared to work.
I then attempted to set my file owner and file group in a PutFile to a user and a group that are each in the LDAP. The PutFile throws a Warning for both owner and group: java.nio.file.attribute.UserPrincipalNotFoundException. The file is still output by the processor. It appears to default the user and owner to nifi. A cursory review of the PutFile source shows that PutFile employs getUserPrincipalLookupService() when it seemingly tries to validate the user and group. How can I get this to resolve through the LDAP for the PutFile? Thanks for any insights. -Jim
