You can change passwords for users whose accounts are in the internal database. You might perform this task if the security of the old password has been compromised. As an alternative, you can force the user to change the password at the next logon. In either case, the new password must meet the requirements defined by the password policy for the user's security domain.
To change passwords for users whose accounts are in an LDAP directory, use the LDAP directory native interface.
In the Security Console, click Identity > Users > Manage Existing.
Use the search fields to find the user that you want to edit. Some fields are case sensitive.
Click the user that you want to edit, and select Edit.
Enter the new password in the Password field.
Enter the new password again in the Confirm Password field.
