Changing the Password for the LDAP Administrator and the LDAP User (including OMS LDAP)

Updated at: Mar 31, 2020 GMT+08:00

Scenario

Periodically change the password for LDAP administrator rootdn:cn=root,dc=hadoop,dc=com and LDAP user pg_search_dn:cn=pg_search_dn,ou=Users,dc=hadoop,dc=com of the MRS cluster to improve the system O&M security.

Impact on the System

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

Procedure

  1. On MRS Manager, choose Services > LdapServer > More.
  2. Click Change Password.
  3. In the Change Password dialog box, select the user that you want to change the password from User Information.
  4. In the Change Password dialog box, enter the old password in Old Password and the new password in New Password and Confirm Password.

    The password complexity requirements are as follows:

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

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

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