在LDAP中搜索用户

Question

I am new to LDAP and trying to write a query to authenticate a user .The root in LDAP is dc=home, dc=alpha, dc=com. There are many groups and users present under dc=home.It is a very deep tree with multiple nested groups and users.I have to use

DirContext(InitialDirContext).search()

api to search the user. I read the specification of

public NamingEnumeration<SearchResult> search(String name,String filter,SearchControls cons)

However i could not find whether it looks for the user recursively inside the specified root,or does it just searche for the first level users or groups.

Answer 1

Use SearchControls.SUBTREE_SCOPE to do it recursively or ONELEVEL_SCOPE for just that level.

    ctx = getContext();
    SearchControls constraints = new SearchControls();
    constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);
    result = ctx.search(searchPath, searchFilter, constraints);

Answer 2

您可以在SearchControls对象中设置所需的深度行为：当前对象，较低一级或整个子树。
