Hi all,
I´m working with the Camel LDAP component. As we can read in the
http://camel.apache.org/ldap.html LDAP page "The result is returned in the
Out body".
I´ve seen in the code of LdapProducer.java (process method), that we only
have this line related to the Out message:
exchange.getOut().setBody(data);
The *problem* here is that, only using this code line, we lose the IN
headers and I need to keep them.
I´ve tried to copy the In headers in the Out headers before calling the LDAP
endpoint using: a processor, the properties exchange, ... but LDAP always
gets this error:
javax.naming.directory.InvalidSearchFilterException: Empty filter; remaining

I only need to add a dummy outHeader to get this LDAP error.
In the end, *the solution* i´ve used to solve this problem is extending the
LDAP component:
<bean id="ldap" class="xxx.ExtendedLdapComponent" />
and i´ve added only this line before calling to the process method in the
LdapProducer,
exchange.getOut().setHeaders(exchange.getIn().getHeaders());
I don´t like this solution but it´s the only one i´ve found to solve it.
Is this a bug in the LDAP Component or the idea of not keeping the headers
is correct?
Thanks
Kind Regards,
Ana Cortés.
