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?
> Recursively drilling into the directory structure causes java.lang.OutOfMemoryError

> 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.
