[ActiveDir] ADAM attribute value

[Harpreet_Kapoor]

We are trying to find the value of the "objectClass" attribute in ADAM. For this we wrote the following code :   char *attrs[2] = {"objectClass", NULL};     LDAPMessage* result = NULL;     int nResult = ldap_search_s (ld, "dc=abcd,dc=com", LDAP_SCOPE_SUBTREE, "objectClass=*", attrs, 0, &result);               if (nResult != LDAP_SUCCESS)     {         return LDAPUTIL_GETVERSIONFAIL;     }       int nentries = ldap_count_entries(ld, result);                 if (nentries <= 0)     {         if (result != NULL)             ldap_msgfree (result);           return LDAPUTIL_SUCCESS;     }       LDAPMessage* e = ldap_first_entry (ld, result);     char** vals = ldap_get_values (ld, e, attrs[0] );     int i=0;             if (vals != NULL)     {         if (vals[i] != NULL)         {                         cout<<"\n val[i] "<<vals[i]<<endl;                         i++;         }         ldap_value_free (vals);     }       if (result != NULL)         ldap_msgfree (result);     nResult = ldap_compare_s (ld, dcRoot, "objectClass","domainDNS");     if  ((nResult == LDAP_COMPARE_TRUE))     {         cout<<"Active Directory Application Mode(ADAM)";         return LDAP_SUCCESS;     }   Actually,our main aim is to find the value of objectClass for ADAM(Active Directory Application Mode)for use in ldap_compare_s().This is why we wrote the code above to find the value of the objectclass parameter.   I have the following questions: 1)We have observed that domainDNS works for Active Directory.Does it also work for ADAM? In our case,it does not.If it does not,what is the attribute value of objectClass in case of ADAM?In my case, ldap_compare_s returns the value 0x10 which means that the attribute does not exist. However,in ADAM ,I can clearly see the attribute.But when I give this value in ldap_compare_s(), it returns the error code 0x10.Is there any other attribute which can be used to identify the dc objects on ADAM just as objectclass and its value domainDNS work for Active Directory. 2)ldap_get_values() returns a NULL .What could be the possible solution?   My configuration settings: Root DN : dc=abcd,dc=com   Thanks, Harry
