First, preface

Let's briefly review the basic concepts of the AD domain and LDAP Directory Access Protocol in the previous blog post.

AD (Active Directory) Active Directory, dynamically establishes a database or index of objects in the entire domain mode network, uses the protocol for LDAP, the server that installs the ad is called the DC domain controller, stores information about the entire domain object, and periodically updates the The objects are divided into three main categories: resources (such as printer), services (such as e-mail), and users (that is, accounts or users, and groups).

It is common for everyone to compare LDAP to a relational database by thinking that LDAP is a different storage method and then comparing it to read performance. In fact, the basis of this comparison is not correct. LDAP and relational database are two different levels of concept, the latter is the storage mode (the same level as network database, object database), the former is the storage model and access protocol. LDAP is a storage concept that is higher than the relational database abstraction level, which is the same level as the query language SQL of the relational database. The most basic form of LDAP is a standard way to connect to a database. This database is optimized for read queries. So it can get query results very quickly, but in other ways, such as updating, it's much slower.

Second, Java gets the AD domain user

Java get AD Domain Users are typically used for single sign On,sso.
