LDAP：错误代码 49 - 80090308：LdapErr：DSID-0C09044E，注释：AcceptSecurityContext 错误，数据 52e，v2580（第一次使用 ldap）

Question

I am having problem with ldap on spring, I know what that error means but idk what i am doing wrong in the config of the connection

this is my application.properties:

spring.ldap.urls=ldap://***
spring.ldap.base=OU=Account,DC=company,DC=lan
spring.ldap.username=CN=Intranet company
spring.ldap.password=pswd

The password are good and username too but maybe my base is false? can anyone help me plz?

and here is what i try to do

@Autowired
private LdapTemplate ldapTemplate;

System.out.println( ldapTemplate.search(
        "OU=Account,DC=company,DC=lan",
        "cn=" + account.username ,
                (AttributesMapper<String>) attrs -> (String) attrs.get("sAMAccountName").get()));

I just try to connect to the active directory and discover how it works

Answer 1

The error message makes it clear that you're using Active Directory. So I'm pretty sure this is the problem:

spring.ldap.username=CN=Intranet company

I don't think Active Directory likes that format for the username. It either has to be:

• The full DN ( CN=Intranet company,OU=Account,DC=company,DC=lan ), or
• The plain username ( sAMAccountName attribute), or
• DOMAIN\username if the user is not on the domain you're connecting to, or
• The userPrincipalName (eg username@company.lan ).
