Give you an example of an LDAP

/* 1. Extract common name CN from LDAP server, distinguished name uid, password userpassword, email address mail
* Using the Netscape LDAP server as a test environment, log on to the LDAP server using simple authentication.
* 2. Using the name ' admin ' password is ' 1 ', the entire program uses the JNDI standard interface in SDK1.4.1.
* 3. To support Domino database development, assume that the IP address of the user at logon is already recorded in the field UID and separated by ', '
* The program will eventually print a string that includes all user names, passwords, and IP addresses.
* 4. The use of regular expressions is introduced in the process of separating user names and IP addresses.
