I have an installation of WSO2 Identity Server and I'm trying to make it work with an external OpenLDAP instance I have followed this guide: http://wso2.org/project/solutions/identity/3.2.3/docs/user-core/admin_guide.html#LDAP For the read-only mode.

But when I try to log-in I get a failed login and the following error on the console:

TID: [0] [WSO2 Identity Server] [2012-08-10 17:10:25,493]  WARN {org.wso2.carbon.core.services.util.CarbonAuthenticationUtil} -  Failed Administrator login attempt 'john[0]' at [2012-08-10 17:10:25,0493] from IP address 127.0.0.1 {org.wso2.carbon.core.services.util.CarbonAuthenticationUtil}

I followed this guide to configure my LDAP server up to Loggging: https://help.ubuntu.com/12.04/serverguide/openldap-server.html

Could you suggest what might be wrong?
