Summary of LDAP development

Write in front

Since the requirement of a recent project is to read some data from the ad domain and then save it to the database, some research has been done on the LDAP thing.

Project requirements

It is known that a node "Cn=authorization2,cn=program Data test,dc=cayzlh,dc=com" needs to get the relevant properties of a node under the node, and then extract it and save it to the database.

Solve the problem

1. Get an LDAP connection
   2. Public class Ldapadhelper {
   4. Private Final String URL = "ldap://" + "192.168.1.204:389";
   6. Private Final String adminname = "[email protected]";
   8. Private Final String AdminPassword = "test123";
   10. Private Ldapcontext CTX = null;
   14. Public Static Ldapadhelper getinstance () throws namingexception{
   16. return New Ldapadhelper ();
   20. }
   22. Private Ldapadhelper () throws namingexception {
   24. this. INITLDAP ();
   26. }
   28. /**
   30. * Initialize LDAP
   32. * @throws namingexception
   34.     */
   36. Private void Initldap () throws namingexception {
   38. //Ad Server
   40. hashtable<string, string> hashenv = new hashtable<string, string> ();
   42. Hashenv.put (Context.security_authentication, "simple"); //LDAP access security level
   44. Hashenv.put (Context.security_principal, this. AdminName); //AD User
   46. Hashenv.put (context.security_credentials, this. AdminPassword); //AD Password
   48. Hashenv.put (Context.initial_context_factory, "com.sun.jndi.ldap.LdapCtxFactory"); //LDAP factory class
   50. Hashenv.put (Context.provider_url, this. URL);
   52. Try {
   54. CTX = new initialldapcontext (hashenv, null);
   56. SYSTEM.OUT.PRINTLN (" Initialize LDAP successfully! ");
   58. } catch (Namingexception e) {
   60. E.printstacktrace ();
   62. System.err.println ("Throw Exception: " + e);
   64. throw E;
   66. }
   68. }
   70. ....
   72. }

Calling the GetInstance () method of this class in an external class can get the helper object and initialize the Ldapcontext object

1. Querying Object Properties
   2. Try {
   4. //domain node
   6. String searchbase = this. Getbasednforroleobject ("cn= role 1,cn=roleobjectdemo2,cn= Msds-azapplicationtest2,cn=authorization2,cn=program Data test,dc=cayzlh,dc=com");
   8. //LDAP search filter class
   10. String searchfilter = "(cn=*)";
   12. //Create a search controller
   14. Searchcontrols searchctls = new searchcontrols ();
   16. //Set search scope
   18. Searchctls.setsearchscope (Searchcontrols.onelevel_scope);
   20. String returnedatts[] = {"distinguishedname "}; ///Custom return property, only query role 1 The DistinguishedName property of this object
   22. Searchctls.setreturningattributes (Returnedatts); //Set return property set
   24. //Do not set to return all properties
   26. //Search LDAP based on domain node, filter class, and search controller set to get results
   28. Namingenumeration<?> answer = Ctx.search (Searchbase, Searchfilter, SEARCHCTLS); //Search
   32. while (Answer.hasmoreelements ()) {//traverse result set
   34. //Get the DN that meets the search criteria
   36. SearchResult sr = (SearchResult) answer.next ();
   38. //Get a qualifying set of properties
   40. Attributes attrs = Sr.getattributes ();
   42. if (attrs! = null) {
   44. Try {
   46. if (Attrs.getall (). Hasmore ()) {
   48. Attribute attr = (Attribute) ne.next (); //Get Next attribute
   50. System.out.println (Attr.getall (). Next (). ToString ());
   52. //The output here is the DistinguishedName property of role 1, if you want to get a property with multiple values, you can use the loop and next () method to get all the values of this property
   54. }
   56. } catch (Namingexception e) {
   58. E.printstacktrace ();
   60. System.err.println ("Throw Exception: " + e);
   62. }
   64. }
   66. }
   68. } catch (Namingexception e) {
   70. System.err.println ("Throw Exception: " + e);
   72. }

Tools

The tools that you use during development are the ADSI Edit to view and edit the corresponding properties in the domain service. Open in the way:

Source

Write a simple demo, is the web version, perhaps some problems, a little change on it. Also need to be able to download to play.

Long time has not sent a blog, the shortcomings of the excuse.
