@LKB  Can you share screenshots of your UpdateAttribute processor configuration? Are you using the advanced UI of the UpdateAttribute processor? The UpdateAttribute processor is fairly simplistic in design. Without configuring the advanced UI, it simply can remove attributes or create/modify existing attributes.  Each Attribute is defined by key:value pairs where the property name is the key and property value is the key.  The Advanced UI allows for conditionally based attribute additions or modifications.

@LKB  I'd expect a full stack trace in the nifi-app.log following that ERROR. The ldap-provider is configured inside the login-identity-providers.xml file.  Does your LDAP Manager password happen to contain any XML special characters?  If so, you should escape them. https://xml.silmaril.ie/specials.html Have you tried using ldapsearch to manually make a connection to your LDAPS from the server where you have NiFi installed using same manager DN, Manager password, and keystore and trustsore?  Was it successful?
