Solve the following python programming problem given the following code:
def _search(self) : 
    c = ldapconnector.LDAPClientCreator (reactor, ldapclient.LDAPClient) 
    d = c.connectAnonymously (self.config.getBaseDN (), self.config.getServiceLocationOverrides ()) 
    def _doSearch(proto) : 
        searchFilter = ldapfilter.parseFilter ('(gn=j*)') 
        baseEntry = ldapsyntax.LDAPEntry (client = proto, dn = self.config.getBaseDN ()) 
        d = baseEntry.search (filterObject = searchFilter) 
        return d 
d.addCallback (self) 
    return d 

    
    

    Fix the buggy line: d.addCallback (self)
