private static void recursivelyDescend(LdapConnection connection,

"(objectclass=*)", SearchScope.ONELEVEL, "*");

recursivelyDescend(connection,
((SearchResultEntry)response).getObjectName().getName());

type " + response);

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.
