Chanaka, thank you very much for your tip! I have an issue during the execution time and I believe that the connector maybe has a problem with its parameters for ldap.init <https://docs.wso2.com/display/ESBCONNECTORS/Configuring+LDAP+Operations>. During the execution of this component an error is gotten by the fault flow:

Look at line 55 in the GitHub <https://github.com/DImuthuUpe/esb-connectors/blob/master/ldap/ldap-connector/ldap-connector-1.0.0/org.wso2.carbon.connector/src/main/java/org/wso2/carbon/connector/ldap/Authenticate.java#L55> and now on a part of my XML: <api context="/SampleContextLdapContext" name="SampleLdapName" xmlns=" http://ws.apache.org/ns/synapse";> <resource methods="POST" protocol="http"> <inSequence> <log description="" separator=","> <property name="Message Flow" value="LDAP SAMPLE TEST"/> <property expression="//myvar/text()" name="myVarValue"/> </log> <ldap.init> <*providerUrl*>ldap://192.168.2.10:389/</*providerUrl*> <*securityPrincipal*>aqlbras\willian</*securityPrincipal*> <*securityCredentials*>SamplePassword</*securityCredentials*> </ldap.init> When I don't configure *providerUrl *the error occurs at line 54, it means that the name parameter is correct for this tag but it's incorrect for securityPrincipal tag (you can see in GitHub <https://github.com/DImuthuUpe/esb-connectors/blob/master/ldap/ldap-connector/ldap-connector-1.0.0/org.wso2.carbon.connector/src/main/java/org/wso2/carbon/connector/ldap/Authenticate.java#L44> to make sure). Have you ever tested it or I am missing something? Thank you for your attention again!
