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

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.

If the LDAP administrator password is changed, the OMS LDAP administrator and user password is changed as well.

  2. Click Change Password.
  3. In the Change Password dialog box, select the user that you want to change the password from User Information.

    • 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 `~!@#$%^&*()-_=+\|[{}];:'",<.>/?
