Error message

LDAPConnection.Exception.GettingAttributes

What it means

Thrown by LDAPConnection.getAttributes() while iterating a SearchResult: fetching the entry's Attributes, or putting the 'dn' value via getNameInNamespace(), failed. It wraps any javax.naming exception raised while materializing a single search result entry. The original naming exception is attached as cause.

Solutions

1. Read the chained cause to identify the exact javax.naming exception (e.g. NameNotFoundException, CommunicationException).
2. Re-run the transformation; transient directory state (entry deleted mid-read) resolves on retry.
3. Check referral handling settings ('follow' vs 'ignore') in the LDAP connection options.
4. Verify the search base and returned entries use valid, fully-qualified DNs.

try { attrs = conn.getAttributes(); } catch (KettleException e) { Throwable cause = e.getCause(); logError("Entry read failed due to " + cause.getMessage(), cause); }

When it happens

Trigger: getSearchResult().next() or searchResult.getAttributes() / getNameInNamespace() throws NamingException during per-row attribute extraction, typically after a successful search (e.g. entry was deleted between paging reads, or referral/name resolution failed).

Common situations: Directory entry removed concurrently mid-iteration, referral chasing to an unreachable server, or invalid DN characters that break getNameInNamespace().
