使用Java列出ldap中的所有sAMAccountName

Question

I want to get the list of all sAMAccountName from ldap, Below is the method which gives me the Ldap attributes of a user by using samAccountName

public static void searchUserFromLdap(String samAccountName) throws Exception{

    SearchResult searchResult = ldapConnection.search("CN=XX,DC=XX,DC=XX", SearchScope.SUB, "(sAMAccountName=" + samAccountName +")"); 

    if(searchResult.getSearchEntries().size()<=0){
        System.out.println("No such user found in LDAP");
        return;
    }

    System.out.println("Start :- LDAP attributes for given user\n");
    for(SearchResultEntry searchResultEntry : searchResult.getSearchEntries()){

        System.out.println(searchResultEntry.toLDIFString());
    }

    System.out.println("\nEnd :- LDAP attributes for given user");

}

This method accept the samAccountName and returns the ldap attributes for user I want to get the list of all samAccountName, I have searched for this but i didn't get anything relevent, Can anyone please tell how can i get the list of sAMAccountName.

Answer 1

I'm not sure what ldapConnection is. Is it from unboundid ?

Either way from the look of the method the third parameter is your LDAP search filter. You can simply change this filter to be the following:

(objectClass=user)

So the method call would be:

SearchResult searchResult = ldapConnection.search(
        "CN=XX,DC=XX,DC=XX", 
        SearchScope.SUB, 
        "(objectClass=user)");

The SearchResult will then contain all users found under CN=XX,DC=XX,DC=XX .

If it is from unboundid, then you can add in a 4th parameter to define that you only want the sAMAccountName ldap attribute to be returned for each result. So this would be:

SearchResult searchResult = ldapConnection.search(
        "CN=XX,DC=XX,DC=XX", 
        SearchScope.SUB, 
        "(objectClass=user)",
        "sAMAccountName");

Answer 2

I am not sure about the above post as i haven't tried it, But after reading the oracle documentation http://docs.oracle.com/cd/E19957-01/816-6402-10/search.htm I modified my search query and it worked, Here is what i have done

public static void getListOfAllSamAccountName() throws Exception {
    List<String> samAccountNameList = null;
    SearchResult searchResult = ldapConnection.search(
            "CN=XX,DC=XX,DC=xx", SearchScope.SUB,
            "(sAMAccountName=*)");

    if (searchResult.getSearchEntries().size() <= 0) {
        System.out.println("No such user found in LDAP");
        return;
    }
    samAccountNameList = new ArrayList<String>();
    System.out.println("Start :- LDAP attributes for given user\n");
    for (SearchResultEntry searchResultEntry : searchResult
            .getSearchEntries()) {
        Attribute attribute = searchResultEntry
                .getAttribute("sAMAccountName");
        String samAccountName = attribute.getValue();

        samAccountNameList.add(samAccountName);

    }

    if (samAccountNameList != null) {
        System.out
                .println("*******************************List of Same account Name******************************");
        for (String samAccountName : samAccountNameList) {

            System.out.println(samAccountName);
        }
    }

    System.out.println("\nEnd :- LDAP attributes for given user");

}
