Question

After following this tutorial https://docs.wso2.com/display/IS410/Connect%2Bthe%2BWSO2%2BAPI%2BManager%2Bto%2Ban%2BExternal%2BLDAP%2BUser%2BStore
to enable the LDAP authentication in WSO2 API Manager I restart the server and appear this error:

But the server start correctly and I can login with the LDAP users. So, how can I control that message or edit the user/password that is referencing in the error because I think that is checking the default wso2 authentication.

Answer 1

This error can happen when using binary data publisher for throttling and the username or password is incorrect. Related configuration is located inside "ThrottlingConfigurations" section of "repository/conf/api-manager.xml" file. Try to update the Username and Password inside the "DataPublisher" configuration to the LDAP user.
<ThrottlingConfigurations>
<EnableAdvanceThrottling>true</EnableAdvanceThrottling>
<DataPublisher>
<Enabled>true</Enabled>
<Type>Binary</Type>
<ReceiverUrlGroup>tcp://${carbon.local.ip}:${receiver.url.port}</ReceiverUrlGroup>
<AuthUrlGroup>ssl://${carbon.local.ip}:${auth.url.port}</AuthUrlGroup>
<Username>user_name</Username>
<Password>password</Password>
....
</ThrottlingConfigurations>
