I wrote the code on Ubuntu 16 and tried to connect to ActiveDirectory on a Windows Server 2012 virtual machine.
The user name is : siwar

The domain name is: squeezer.celtron.com
The VM host address (Windows server 2012) : 192.168.1.115
The following code did not work and generated an Authentification:

I'm newer coding ldap using spring-boot (ldapTemplate). I want to get the groups that a user belongs, get the list of membreOf attributes, I tried this:
#Override
public Person getUserInfo(String uid, String orgnisationUnit) throws InvalidNameException {
Name dn = bindDn(uid, orgnisationUnit);
return (Person ) ldapTemplate.lookup(dn, new LdapMapper());
}
This is myLdapMapper:
public class LdapMapper implements ContextMapper<Object> {
#Override
public Object mapFromContext(Object ctx) {
DirContextAdapter context = (DirContextAdapter) ctx;
Person p = new Person();
p.setFirstName(context.getStringAttribute("cn"));
p.setMailAddress(context.getStringAttribute("uid"));
p.setRoles(context.getObjectAttributes("memberOf")); // roles was declared like: private Object[] roles
return p;
}
}
Would you have any propositions ?

I hope this code will solve you problem.
When i am trying to search password of user from ldap server this
below error displayed
In this code its doesn't return user Password in String. It throws
java.lang.ClassCastException: [B cannot be cast to java.lang.String

}
}
LDAP passwords are stored as hashes, not strings. The attribute value is returned as a byte[], as the exception says.
However you don't have any good reason for obtaining the hashed password attribute in the first place. It won't do you any good. Review your requirement. You should be binding as the user using the old password to test whether it's valid, not trying to read the password, which you won't get.
Retreiving binary attributes requires the ;binary suffix, e.g., userCertificate;binary. Then you have the Attribute object. Invoke
byte[] bytes = (byte[]) attr.get()
and you are done. Don't work with toString() or (String) cast.
I have to check if username and password gave from user are right matching with the Ldap server. I use two connection, in the first I retrieve dn from uid and in the second I connect to Ldap with dn and password.
I have a problem with retrieved dn, it doesn't have the right fields.
It returns
cn=Lu Ca+sn=Ca+uid=luca+userPassword={SSHA}OiMBVTTZBPqnohYch9\+ISeVv\+5ucgxMR: null:null:No attributes
and not
cn=Lu Ca+sn=Ca+uid=luca+userPassword={SSHA}OiMBVTTZBPqnohYch9\+ISeVv\+5ucgxMR,ou=people,dc=example,dc=com
As you can see, ou and dc are not returned so my second query fails.
This is my code
#Override
public void isAuthenticated(String username, String password) throws LdapException{
String dn;

with this parameters
ldap.url=ldap://127.0.0.1:10389/dc=example,dc=com
ldap.userSearchBase=ou=people
I'm uing this value also for spring authentication but I have one method (send big file) that fails only if I use authentication so I would like to try to authenticate with java and not through Spring
Do you know why I have this problem? thanks
UPDATE: with
dn = results.nextElement().getNameInNamespace();
it works, is my codes robust?

You're not looping, so of course you're only getting one result. Change if (answer.hasMore()) to while (answer.hasMore()).
I am making a log in form on java. Restful web service. I have done logging in and in registration. I have here inputting plate number. I want to retrieve data based on the inputted plate number. I have here the scanning only of the plate number if it is in the database, but I dont know how to display the details of it. Here's my code. I'm so confused. I don't know how to do it.
