Domino® server and Notes® user IDs
Domino® uses ID files to identify users and to control access to servers. Every Domino server, Notes® certifier, and Notes user must have an ID.
Notes® ID vault
The ID vault is an optional, server-based database that holds protected copies of Notes® user IDs. An ID vault allows administrators and users to easily manage Notes user IDs. Users are assigned to a vault through policy configuration, and copies of user IDs are uploaded to a vault automatically once the policy has taken effect.
Planning an ID vault deployment
The topics in this section provide information to help you plan an ID vault deployment.
Authorization for ID downloads
To help thwart unauthorized access to ID files, you can choose to require that someone with password reset authority approve all ID downloads by specifying a number of downloads allowed (a download count).

  - Overview of Domino security
    Setting up security for your organization is a critical task. Your security infrastructure is critical for protecting your organization's IT resources and assets. As an administrator, you need to give careful consideration to your organization's security requirements before you set up any servers or users. Up-front planning pays off later in minimizing the risks of compromised security.
  - Server access for Notes® users, Internet users, and Domino® servers
    To control user and server access to other servers, Domino® uses the settings you specify on the Security tab in the Server document as well as the rules of validation and authentication. If a server validates and authenticates the Notes® user, Internet user, or server, and the settings in the Server document allow access, the user or server is allowed access to the server.
  - The database access control list
    Every .NSF database has an access control list (ACL) that specifies the level of access that users and servers have to that database. Although the names of access levels are the same for users and servers, those assigned to users determine the tasks that they can perform in a database, while those assigned to servers determine what information within the database the servers can replicate. Only someone with Manager access can create or modify the ACL.
  - Domino® server and Notes® user IDs
    Domino® uses ID files to identify users and to control access to servers. Every Domino server, Notes® certifier, and Notes user must have an ID.
    - Certificates
      A certificate is a unique digital signature that identifies a user or server. Server and user IDs contain one or more HCL Notes® certificates. In addition, user IDs may contain one or more Internet certificates that identify users when they use SSL to connect to an Internet server or send a signed S/MIME mail message.
    - Notes clients and two-factor authentication
      HCL Notes client authentication with a Notes ID provides built-in, automatic, two-factor authentication.
    - Password-protection for Notes® and Domino® IDs
      To ensure the security of the Domino® system, password-protect all Notes® and Domino IDs -- certifier, server, and user. When you password-protect an ID, a key that is derived from the password encrypts the data on the ID. Then, when you attempt to access mail, open a server-based database, or examine ID file information, you are prompted to enter a password.
    - The password quality scale
      When creating passwords for user, server, or certifier IDs, you need to understand the criteria by which Domino® measures password strength and security. Domino measures this criteria according to the level assigned on its password quality scale. The scale assigns a minimum level of quality to the password on an ID file. Domino bases the password quality on the number and variety of characters in the password.
    - Verifying user passwords during authentication
      You can enable password verification so that a Notes® user can authenticate with a server only after providing the correct password that is associated with the user ID.
    - Setting up password verification
      You can enable password verification through the use of a security policy settings document, which allows you to enable this feature for multiple users, or you can enable password verification on an individual basis through the Domino® Directory.
    - Custom password policies
      Information protection and data privacy laws include specific requirements for the selection of secure passwords for identity verification. To help users comply with these laws, HCL Domino® includes the ability to implement password restrictions on a policy basis. Administrators can enforce password requirements that will fit almost any set of corporate or government security requirements.
    - Assigning multiple passwords to server and certifier IDs
      To assign multiple passwords to server and certifier IDs, all of the administrators whose passwords will be assigned to the ID must be present. Then, during the procedure of assigning multiple passwords, each administrator completes a series of steps.
    - Using Notes® Shared Login (NSL) to suppress password prompts
      Notes® Shared Login (NSL) allows users to start Notes without having to provide Notes passwords. Instead, they only need to log in to Microsoft™ Windows™ using their Windows passwords.
    - Using Notes® Client Single Logon to synchronize Notes® and Windows™ OS passwords
      You can use Notes® Client Single Logon to synchronize your Notes users' Microsoft™ Windows™ passwords with their Notes passwords, allowing them to use the same password.
    - Notes® ID vault
      The ID vault is an optional, server-based database that holds protected copies of Notes® user IDs. An ID vault allows administrators and users to easily manage Notes user IDs. Users are assigned to a vault through policy configuration, and copies of user IDs are uploaded to a vault automatically once the policy has taken effect.
      - How an ID vault works
        This topic describes common vault operations.
      - ID vault security
        An ID vault provides several layers of security.
      - Planning an ID vault deployment
        The topics in this section provide information to help you plan an ID vault deployment.
        ID vault limitations
        Be aware of the following current ID vault limitations.
        ID vault trust
        User IDs can be stored in an ID vault only if a parent certifier of the IDs has been used to issue a Vault Trust Certificate to the vault. A Vault Trust Certificate is a special-purpose cross-certificate establishing that an organizational or organizational unit certifier trusts an ID vault to store the user IDs that are descended from the certifier.
        ID vault password reset security
        A benefit of the vault is the ability to easily reset passwords on IDs when users forget them. There are two models available for resetting passwords: authorized personnel can use the Domino® Administrator to reset passwords for users, or users or authorized personnel can reset passwords using a custom application. You can implement one or both models.
        Security for server ID files and the vault ID file
        The Notes® ID vault server's ID file is integral to the protection of the vault's contents. Because someone who gains access to a vault server ID file could potentially gain access to vault data, it is vital to restrict access to the server ID files of vault servers.
        Authorization for ID downloads
        To help thwart unauthorized access to ID files, you can choose to require that someone with password reset authority approve all ID downloads by specifying a number of downloads allowed (a download count).
        ID vault servers
        An ID vault server is a server with a vault replica. The first vault server is created when the vault is created using the ID Vaults > Create tool. Vault administrators create additional vault servers using the ID Vaults > Manage tool in the Domino® Administrator.
        ID vault management roles
        Domino® administrator access is required to perform all vault configuration and management tasks, with the following exceptions.
        ID vault backup and recovery
        Back up ID vault databases using your preferred backup method and media. If a vault database becomes corrupted, use either of the following methods to restore it.
      - ID vault FAQs
        Here are answers to some frequently asked questions about the ID vault.
      - Creating and configuring an ID vault
        To make an ID vault operational you must create the vault database on a server, create the vault ID file, specify at least one vault administrator, specify which user organizations trust the vault, assign password reset authority, and use policies to assign user IDs to the vault.
      - Deleting an ID vault
        You can delete an ID vault. Before doing that you must delete all replicas except the one on the vault primary server.
      - Viewing user IDs in a vault
        After users have been assigned to a vault through a policy, the next time they start Notes® after the policy has taken effect, their IDs are uploaded to the vault. Note that there may be a delay before policy changes take effect.
      - Maintaining ID file synchronization
        When passwords on Notes® client IDs become different from the passwords on the IDs in the ID vault, synchronization of ID information between clients and the ID vault stops. You can enable automatic restarting of synchronization when the passwords get out of sync. You can use the Query Vault console command or the Domino Administrator to monitor and manage ID synchronization.
      - Managing the user IDs in an ID vault
        You can reset the password of an ID stored in a vault, specify the number of ID downloads a user is allowed, extract an ID from a vault for auditing purposes, delete an ID from a vault, or mark an ID in a vault as inactive.
      - Troubleshooting an ID vault configuration
        There are two ways to troubleshoot problems with an ID vault, do either or both of the following:
      - ID vault NOTES.INI settings
        The following NOTES.INI settings pertain to the ID vault.
    - ID recovery
      Use of the ID vault for ID recovery is strongly recommended. However, the ID recovery feature described in this topic is still supported.
    - Public key security
      Every Notes® user ID and Domino® server ID has a unique public key for the Notes certificate. The public key is stored in an ID file and in the Person or Server document for that ID in the Domino Directory. Notes and Domino use the public key to authenticate users and servers, verify digital signatures, and encrypt messages and databases. A Notes user ID can also have a unique public key for an Internet certificate.
    - User and server key rollover
      Key rollover is the process used to update the set of Notes® public and private keys that is stored in user and server ID files. Periodically, this set of keys may need to be replaced -- as a precaution against undetected compromise of the private key; as a remedy to recover from a known compromise of the private key; or to increase security by updating to a larger key.
    - Certificate authority key rollover
      HCL Domino® administrators can assign a new set of public and private keys to a Domino certificate authority (CA). These keys are used to certify the keys of OUs, servers, and users in that organization. The process of assigning news keys is known as key rollover.
    - Using cross-certificates to access servers and send secure S/MIME messages
      Domino® uses both Notes® and Internet cross-certificates. Notes cross-certificates allow users in different hierarchically-certified organizations to access servers and to receive signed mail messages. Internet cross-certificates allow users to receive signed mail messages and send encrypted mail messages.
    - Adding cross-certificates to the Domino® Directory or Contacts
      You can use several methods to obtain an HCL Notes® or Internet cross-certificate.
  - The execution control list
    You use an execution control list (ECL) to configure workstation data security. An ECL protects user workstations against active content from unknown or suspect sources, and can be configured to limit the action of any active content that does run on workstations.
  - Domino® server-based certification authority
    You can set up a Domino® certifier that uses the CA process server task to manage and process certificate requests. The CA process runs as a process on Domino servers that are used to issue certificates. When you set up a Notes® or Internet certifier, you link it to the CA process on the server in order to take advantage of CA process activities. Only one instance of the CA process can run on a server; however, the process can be linked to multiple certifiers.
  - SSL security
    Secure Sockets Layer (SSL) is a security protocol that provides communications privacy and authentication for Domino® server tasks that operate over TCP/IP.
  - SSL and S/MIME for clients
    Clients can use a Domino® certificate authority (CA) application or a third-party CA to obtain certificates for secure SSL and S/MIME communication.
  - Encryption
    Encryption protects data from unauthorized access.
  - Name-and-password authentication for Internet/intranet clients
    Name-and-password authentication, also known as basic password authentication, uses a basic challenge/response protocol to ask users for their names and passwords and then verifies the accuracy of the passwords by checking them against a secure hash of the password stored in Person documents in the Domino® Directory.
  - Multi-server session-based authentication (single sign-on)
    Multi-server session-based authentication, also known as single sign-on (SSO), allows Web users to log in once to a Domino® or WebSphere® server, and then access any other Domino or WebSphere servers in the same DNS domain that are enabled for single sign-on (SSO) without having to log in again.
  - Using Security Assertion Markup Language (SAML) to configure federated-identity authentication
    Federated identity is a means of achieving single sign-on, providing user convenience and helping to reduce administrative cost. In Domino® and Notes®, federated identity for user authentication uses the Security Assertion Markup Language (SAML) standard from OASIS.
  - Using a credential store to store credentials
    A Domino® server can use a credential store application as a secure artifact repository. Examples of secure artifacts include authentication credentials and security keys.

Authorization for ID downloads

To help thwart unauthorized access to ID files, you can choose to require that someone with password reset authority approve all ID downloads by specifying a number of downloads allowed (a download count).

Either of the following events is considered an ID download:

Recovery from a missing ID file
Recovery from a forgotten password

You use policy configuration to require authorization for ID downloads, to specify a download time limit that applies to all users of the policy, and to specify help text to display to users when either a download time limit or download count limit has been exceeded.

You specify a download count limit on a per-user basis through HCL Domino® Administrator tools. For example, if a user runs HCL Notes® from two computers, you might specify a download count of 2 for that user. To require authorization for any ID download, specify 0 as the download count and then increase the count when needed to authorize a specific download or downloads.
