I try to use LDAP authentication. 

public boolean login(String username, String password){
    AndFilter filter = new AndFilter();
    filter.and(new EqualsFilter("objectclass", "person")).and(new EqualsFilter("uid", username));
    return ldapTemplate.authenticate(DistinguishedName.EMPTY_PATH, filter.toString(), password);
}

Because I used ActiveDirectory server, I have this exception:

javax.naming.NamingException: [LDAP: error code 1 – 000020D6: SvcErr: DSID-03100754, problem 5012 (DIR_ERROR), data 0]; remaning name = ‘/’

In my opinion, this exception showed, because I use DistinguishedName.EMPTY_PATH.

How I can to fix this problem?

    The actual error you have is the following:

    //
// MessageId: ERROR_DS_MISSING_SUPREF
//
// MessageText:
//
//  No superior reference has been configured for the 
//  directory service. The directory service is therefore 
//  unable to issue referrals to objects outside this forest.
//
#define ERROR_DS_MISSING_SUPREF          8406L

    This can be found by converting the error code you have (000020D6) into decimal and checking in winerror.h.

    In my opinion you need to supply a base DN for the search you are performing. The one you have supplied (supposedly by default, when not specified) is /, which is not a valid DN. If you domain name is domain.example.com, a valid base DN will be DC=domain,DC=example,DC=com.
