Changing the Passwords of the LDAP Administrator and the LDAP User

Updated at: Mar 25, 2021 GMT+08:00


This section describes how to periodically change the passwords of the LDAP administrator rootdn:cn=root,dc=hadoop,dc=com and the LDAP user pg_search_dn:cn=pg_search_dn,ou=Users,dc=hadoop,dc=com to improve the system O&M security.

Impact on the System

All services need to be restarted for the new password to take effect. The services are unavailable during the restart.


  1. On MRS Manager, choose Services > LdapServer > More.
  2. Click Change Password.
  3. In the Change Password dialog box, select the user whose password needs to be modified in the User Information drop-down box.
  4. Enter the old password in the Old Password text box, and enter the new password in the New Password and Confirm Password text boxes.

    The default password complexity requirements are as follows:

    • The password contains 16 to 32 characters.
    • The password must contain at least three types of the following: uppercase letters, lowercase letters, digits, and special characters (`~!@#$%^&*()-_=+\|[{}];:",<.>/?).
    • The password cannot be the username or the reverse username.
    • The new password cannot be the same as the current password.

    The default password of the LDAP administrator rootdn:cn=root,dc=hadoop,dc=com is LdapChangeMe@123, and that of the LDAP user pg_search_dn:cn=pg_search_dn,ou=Users,dc=hadoop,dc=com is pg_search_dn@123. Periodically change the passwords and keep them secure.

  5. Select I have read the information and understand the impact, and click OK to confirm the modification and restart the service.
