Sebu Koleth commented on DIRAPI-13:
-----------------------------------
In contrast I have been using plain JNDI code with a few enhancements to do the
same thing and it works without any problem. So does the Unboundid LDAP SDK. So
would a re-think of the LDAP Client API be in order?

> The above piece of code is exercised after obtaining an SSL-based LDAP
> connection. The target server has hundreds of thousands of records at
> different levels. Logging at WARN level shows a *lot* of messages :
> WARN NioProcessor-1 org.apache.directory.shared.asn1.ber.Asn1Decoder - The
> PDU has been fully decoded but there are still bytes in the buffer.
> The code chokes at processing the 52nd entry that is two levels deep from the
> base DN. At this level there are around 1000 sub-levels.
