A more flexible way should be established to handle info/warning/error codes.
As this is in most cases the problem domain of the surrounding application, ResultMappers would probably be a better solution.

bool LDAPAbstractDAI::Exec( Context &ctx, ParameterMapper *getter, ResultMapper *putter)
{
    StartTrace(LDAPAbstractDAI.Exec);
    Trace("Executing LDAP data access: " << fName);
    LDAPErrorHandler eh(ctx, getter, putter, fName);

    bool ret( false );
    if ( (ret = DoExec(ctx, getter, putter, eh)) == true ) {
        // LDAP transaction completed successfully
        return ret;
    }
    if ( eh.GetRetryState() == LDAPErrorHandler::eRetry ) {
        Trace("Will try a rebind (LDAP might have been restarted.) for DataAccess: " << fName);
        eh.HandleSessionError((LDAP *) NULL, "Will try a rebind (LDAP might have been restarted.)");
        eh.CleanUp();
        eh.SetRetryState(LDAPErrorHandler::eIsInRetrySequence);
        return DoExec(ctx, getter, putter, eh);
    }
    return ret;
}
