Hi According to the code, Connector throws an exception when there is no result set found while searching the users. Not on error in connector. This seems to be invalid because It should not throw an exception by checking null. It should set a message and let the message flow continue. Searching may or may not contains user informations and the message flow should be decided by the developer, how It continue based on the result. However we have implemented it in a way that goes to fault sequence on empty result set and developer has no control.
However It would be better if we can fix this code. To maintain backward compatibility, we can introduce a property(faultOnEmptyResult) and based on the property, we can decide whether it goes to fault or continue message flow. As a default behavior, we can set faultOnEmptyResult to true. Then existing develpers does not affect this change and backward compatibility remains.  https://github.com/wso2-extensions/esb-connector-ldap/blob/org.wso2.carbon.connector.ldap-1.0.3/src/main/java/org/wso2/carbon/connector/ldap/SearchEntry.java#L80 Thanks, Nuwanw On Mon, Apr 9, 2018 at 2:06 PM, Piriya Sivalingam <pir...@wso2.com> wrote: > Hi, > > In the LDAP connector, if we encounter any exception , it throws the > synapseException.
