Emmanuel Lecharny commented on DIRSERVER-2163:
----------------------------------------------
Ok, so you are just using ApacheDS as a way to get LDAP requests, and to send
LDAP requests, regardless to what they do. That's fine, it would have been a
valuable information to provide in you first post.
Now, again, you are on your own. The message you get means the encoding of your
response is incorrect. It's not caused by ApacheDS in any way. When ApacheDS
encodes an extended operation, it has no knowledge about the payload (in your
case the content of the 'response' part of the extendedResponse).
Would you provide the PDU that causes the issue, and the complete description
(in ASN.1 form) of your extended operation we might be able to give a clue
about what's going on, but with the provided information, we can't do anything.
