Reference: User Administration menu
Use TanOS to manage user accounts on the Tanium appliance. Users with the tanadmin role can manage two types of user accounts:
-
Use the TanOS User Management menu (C-U) to manage TanOS system users. These user accounts can access the TanOS console, but not the Tanium™ Console. This includes the predefined TanOS users tanadmin and tancopy. TanOS system users are local to each appliance; users are not shared across appliances. You can optionally use your enterprise LDAP server to manage TanOS authentication. For details on using LDAP for TanOS users, see Configure LDAP authentication for TanOS system users.
For more information on the predefined TanOS user accounts, see Completing the initial setup (Tanium Physical Appliance), Completing the initial setup (Tanium Virtual Appliance), or Completing the initial setup (Tanium Cloud Appliance).
- Use the Local Tanium User Management menu (C-L) to manage Tanium users who can access the Tanium Console through a web browser. These user accounts cannot access the TanOS console. TanOS hosts a local authentication service that you can use for Tanium Console user authentication. In addition, you can use your enterprise LDAP server to manage Tanium Console authentication. For information about using LDAP for Tanium users, see Tanium Console User Guide: Integrating with LDAP servers.
Change TanOS user passwords
The tanadmin user can make password-authenticated SSH connections to the TanOS console.
Change the tanadmin password
Use these steps to reset the password for the current tanadmin user. On TanOS 1.7.3 or later, the password reset prompt appears if the tanadmin user password expires. To change the password for another tanadmin user, see Manage system users.
- Sign in to the TanOS console as a user with the tanadmin role.
- Enter P and follow the prompts to change the password.
View screen
After the password changes, you are signed out.
Manage SSH keys
The installation process generates a public/private SSH key pair for the tanadmin user. Use the User Administration menus to perform the following functions:
- Regenerate the key pair.
- Generate keys for the other TanOS special users.
- Add authorized keys to support inbound user connections.
- View the public key so you can copy and paste it into other appliance configurations.
You can use ssh-copy-id to add an SSH public key to any TanOS user with the tanadmin role.
Before you begin

Configure LDAP authentication for TanOS system users
You can optionally configure an LDAP connection to use Active Directory or another directory service to manage TanOS system users.
-
You cannot delete the tanadmin and tancopy special users. These user accounts are always administered locally within TanOS. Even if an LDAP query returns either of these user names, the locally administered user and associated password takes precedence.
- This LDAP configuration applies only for authentication in the TanOS console. For information about using LDAP for Tanium users, see Tanium Console User Guide: Integrating with LDAP servers.
Manage the authentication certificate for the LDAP server
TanOS requires TLS encryption using StartTLS for communication with the LDAP server. You must import the LDAP server root certificate authority (CA) certificate. The certificate must be in PEM format. On the appliance, you have the option to paste the contents of the LDAP server root CA certificate or import the file.
If you import a new certificate after you have already configured LDAP server connection settings, you must re-enter the bind credentials for the connection. For more information, see Configure specific LDAP connection settings.
Option 1: Paste the LDAP server root CA certificate Contents
- Sign in to the TanOS console as a user with the tanadmin role.
- Enter C to go to the User Administration menu.
- Enter A to go to the AD/LDAP TanOS Authentication menu. View screen

-
Enter A to go to the AD/LDAP TanOS Authentication menu.
- Enter C to go to the Configure AD/LDAP TanOS Authentication menu. View screen
-
Use the menu options to modify the following settings as necessary:
Setting Menu Key Description Enable E Specifies whether LDAP authentication is enabled for authenticating TanOS system users. For more information, see Enable or disable LDAP authentication. Domain D The domain by which the system and logs refer to the LDAP configuration. This setting does not affect the connection to the LDAP server Host H The host name of the LDAP server
-
TanOS requires TLS encryption for communication with the LDAP server. The host name configured for this setting must match the common name or subject alternative name in the TLS certificate presented by the LDAP server. An IP address is not usually not valid.
- If you change the host name in an existing configuration, you must re-enter the bind credentials for the connection. (Enter C from the Configure menu.)
Port P The port on which to connect to the LDAP server
This is typically port 389.
If you change the port number in an existing configuration, you must re-enter the bind credentials for the connection. (Enter C from the Configure menu.)
Bind Credentials C The user name used to sign in to and query the LDAP server in a format accepted by the server, and the password for the user name
The following user name formats are commonly used, depending on the configuration of your Active Directory or LDAP server:
-
User principal name (UPN): user@domain.name
- Down-level logon name: DOMAIN\user
- Distinguished name (DN): CN=user, DC=domain,DC=tld
Base Search DN B The base DN from which TanOS queries the directory
Schema S The schema used by the LDAP server. TanOS supports Active Directory, RFC2307, RFC2307bis, Red Hat Identity Manager (IdM), and FreeIPA. Referrals Q Specifies whether TanOS allows the LDAP server to refer the query to other connected LDAP servers when you have multiple LDAP servers in your organization
- Referrals can significantly increase the time required to process a query.
-
TanOS does not always allow a user returned from a referral to sign on, depending on the configuration of the directory.
SSH Public Key Attribute K The LDAP attribute that contains the SSH public key for each user
The user that is specified for the Bind Credentials setting must have read access to this attribute.
This attribute is commonly sshPublicKey.
Users Filter U The LDAP search filter to use to limit the users that the LDAP server returns for the query. Leave this setting blank to return all users under the base search DN.
Most LDAP servers do not support using wildcard characters or nested groups with the MemberOf attribute in a filter.
Groups Filter G The LDAP search filter to use to limit the groups that the LDAP server returns for the query. Leave this setting blank to return all groups under the base search DN. TanOS Roles Mapping M The LDAP users or groups that map to the tanadmin and tanuser roles. If TanOS can successfully connect to the LDAP server when you configure this setting, it displays a list of valid users or groups and then validates the users or groups that you enter with the server.
Enter A to go to the tanadmin Mappings menu and manage the users or groups that map to the tanadmin role. Users in these groups have access to all TanOS menus.
View screenEnter U to go to the tanuser Mappings menu and manage the users or groups that map to the tanuser role. Users in these groups have access to TanOS status menus.
View screen-
Avoid assigning users in the directory to both a group that is mapped to the tanadmin role and a group that is mapped to the tanuser role. If a user is assigned both roles, the user can perform most administrative tasks in TanOS, but permissions might be unpredictable. You can review users with conflicting mappings in the Detailed Status report. For more information, see View the LDAP connection status and query results.
-
You cannot delete the tanadmin and tancopy special users. These user accounts are always administered locally within TanOS. Even if an LDAP query returns either of these user names, the locally administered user and associated password takes precedence.
