Name dn = buildDn(user);
ldapTemplate.bind(dn, null, buildAttributes(user));
}

Answer 1

I have solved this problem.
1.I checked the log file of ldap admin, and I saw the "dn":
ou=Users,dc=xinsight,dc=com,dc=xinsight,dc=com
2.before and after
return LdapNameBuilder.newInstance(Base_DN)
.add("ou", "Users")
.add("uid","lyh3")
.build();
return LdapNameBuilder.newInstance()
.add("ou", "Users")
.add("uid","lyh3")
.build();
And after I removed the param: Base_DN, I created a user successfully. Then I check the log file of ldap admin, it shows that:
dn: ou=Users,dc=xinsight,dc=com
Although I don't know why the value of dn has duplicate 'dc=xinsight,dc=com'. I copied from the official document spring-ldap official doc, and it shows that a 'base_dn' is needed when building 'dn':
protected Name buildDn(Person p) {
return LdapNameBuilder.newInstance(BASE_DN)
.add("c", p.getCountry())
.add("ou", p.getCompany())
.add("cn", p.getFullname())
.build();
}
