LDAP: error code 49 - 80090308: LdapErr: DSID-0C09042F, comment: AcceptSecurityContext error, data 52e, v2580

I know "52e" code is when username is valid, but password is invalid. I am using the same user name and password for validating user against Active directory and its working fine.

Here is my java code:

        String userName = "user_test";
        String password =  "*******";
        String base ="DC=test,DC=local";
        String dn = "cn="+ userName + "," + "CN=Users," + base;  

        try {
            Hashtable env = new Hashtable();
            env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
            env.put(Context.SECURITY_AUTHENTICATION, "simple");

            env.put(Context.SECURITY_PRINCIPAL, dn);

            env.put(Context.SECURITY_CREDENTIALS, password);

            env.put(Context.PROVIDER_URL, "ldap://*****.test.local:389");


            System.out.println("Attempting to Connect...");

            ctx = new InitialLdapContext(env, null);
            System.out.println("Connection Successful.");
        } catch (NamingException nex) {
            System.out.println("LDAP Connection: FAILED");
            nex.printStackTrace();
        }
        return ctx;
    }

I do not know exactly why getting this error. Can anyone please help on this?

Answer 1

In case you use simple authority authentication , you should use short username form

user_test@test.local

I checked, in this case authentication is working. In dn form I have got exactly the same error

javax.naming.AuthenticationException: [LDAP: error code 49 - 80090308: LdapErr: DSID-0C0903A9, comment: AcceptSecurityContext error, data 52e, v1db1

You may also refer to earlier thread LDAP: error code 49 - 80090308: LdapErr: DSID-0C0903A9, comment: AcceptSecurityContext error, data 52e, v1db1

The error is pretty definitive.

49 52e 1326 ERROR_LOGON_FAILURE Returns when username is valid but password/credential is invalid.

Often the Hard Part is properly determining the DN .
