DESCRIPTION
The bpnbat command is a tool that enables a user to use the Veritas Product Authentication and Authorization Service.
This service contains the following two distinct parts:
Authentication - prove who you are
Authorization - check what you can do
bpnbat enables a user to do authentication tasks from within NetBackup.
If a command needs a password, it doesn't echo the password or asterisks, which someone can use to narrow the password search space significantly.
NetBackup Access Control requires the user's home directories to work correctly.
You must have administrator privileges to run the following command options: -AddDomain, -RemoveDomain, -AddMachine, -AddUser, -RemoveUser, -LoginMachine, and -ShowMachines.
OPTIONS
- [-AddDomain | -RemoveDomain] Private_Domain
These options enable an administrator that runs locally on an Authentication server to add or remove domains within the private Veritas Domain Database. These domains are not accessible from within any operating system. They are meaningful only within Veritas Product Authentication and Authorization Service. Use them where a centralized naming authority (such as a PDC/AD or NIS domain) is not available.
- -AddMachine
Registers a computer in a private Veritas Product Authentication. The identity is placed in the private domain NBU_Machines@at.server.name. Run this option on your authentication broker (root +ab).
- [-AddUser | -RemoveUser] Private_Domain
Enables an administrator that runs locally on an Authentication server to add or remove users from domains in the private Veritas Domain Database. These accounts are meaningful only within Veritas Product Authentication and Authorization Service. Use them when a centralized naming authority (such as PDC/AD or NIS domain) is not available.
- -GetBrokerCert
Obtains a broker certificate without authenticating to a broker.
- -Login [-Info answer_file] [-cf credential_file] [-LoginType AT|WEB]
Identifies yourself to the system. When you run this command with no options, you are prompted to enter a name, password, domain, authentication type, and a server to authenticate. The combination of a name, password, domain, and domain type creates a unique identity within an Enterprise-wide network. The first time a broker is contacted, you are asked if you want to trust that broker and authenticate them. You cannot use an untrusted broker.
Note:
You must use the bpnbat -login command to perform certain authorization token and host ID-based certificate-related operations. You must have NetBackup administrator privileges to do a web logon.
The -Info option accepts the name, password, and domain information from an answer file. The password is optional in the answer file. You can also place the certificate in a credential file (if specified) or the default location. If you do not provide a password, you are prompted for the password when you run the command.
Warning:
Saving the user name and password in a plain text file is a potential security issue. Unauthorized users with read access to the text file can obtain the user name and password for the Veritas Product Authentication and Authorization Service to manually authenticate with the bpnbat command. Make certain that you secure access to the answer text file.
The answer file is a text file with entries for the required information. The answer file must contain the four lines that are shown in the order shown:
domain type domain user name password
A sample answer file is:
NT Sample_Domain administrator s@Mpl3
As previously explained, password is an optional value. The domain type value must be one of the values shown:
NIS
NIS+
NT
vx
unixpwd
If you use an answer file, ensure that the appropriate AUTHENTICATION_DOMAIN is configured on the server. See the NetBackup Security and Encryption Guide.
The NetBackup Web Management Console Service (
nbwmc
) always runs on the NetBackup master server. The Authentication Broker normally runs on the NetBackup master server as well. But in certain instances, it can run on a host other than the master server.If the -LoginType is AT, only a NetBackup AT broker logon for the master server is performed. If the -LoginType is WEB, only a NetBackup web application logon for the Authentication Broker is performed. If the -LoginType is not specified, both the AT and the WEB logons are performed if the Authentication Broker is on the master server. If the -LoginType is not specified and the Authentication Broker is not on the master server: the WEB logon succeeds and the AT logon fails. The AT logon fails with a security services status code 96. The - cf option is not applicable if the -LoginType is WEB.
- -LoginMachine
Identifies a computer that uses an account within the Veritas Security Subsystem private domain NBU_Machines@at.server.name. Run this option on your NetBackup Media, Master, and Clients. This option is similar to when you log on as a user to an authentication broker.
- -Logout [-cf credential_file] [-LogoutType AT|WEB]
Invalidates the current user credentials that require the user to log on again to continue. Without the -cf option, the credential that is stored at the default location is expired. The -cf option points to the actual credential file, which allows a user to explicitly specify the credential to be expired.
If the -LogoutType is AT, only a NetBackup AT broker logout is performed. If the -LogoutType is WEB, it is a NetBackup web application logout. If the -LogoutType is not specified, both the AT and the web logout are performed. The - cf option is applicable only for the AT logout.
- -RemoveBrokerCert server.name.com
Removes a trust of a specified authentication broker for all users except the root user (administrator). You can use this command to remove a broker when you no longer trust it. For example, an authentication broker is moved to a different corporate division.
- -RenewCred [-cf credential_file]
Renews the current user credentials from the VxSS store or the credential file that is specified with the -cf option.
- -ShowBrokerCerts
Lists all of the brokers that the user currently trusts. NetBackup trusts any broker that is listed to handle the authentication requests that are sent to it.
- -ShowMachines
Lists all computers that have been added to the computers domain of a private Veritas Security Subsystem database by using the -AddMachines option. It also shows if DNS fully resolved the computer name. Run this option on your authentication broker (root +ab).
- -Version
Retrieves the version of the executable.
- -WhoAmI [-cf credential_file] [-Verify]
Specifies the identity you currently use within Veritas Product Authentication and Authorization Service. It lists the following:
Name
Domain
Authentication broker who issued the credential
The time a certificate expires
The domain type that was used when the credential was created
EXAMPLES
Example 1 - The user uses -Login and the default port number to connect to the authentication broker that is called test.domain.veritas.com. (It is the server that handles the Authentication process.) An NIS account is used. Therefore, a domain name that is associated with the NIS account is provided in addition to a user and password.
# bpnbat -Login Authentication Broker: test.domain.veritas.com Authentication port[ Enter = default]: Authentication type (NIS, NISPLUS, WINDOWS, vx, unixpwd): NIS Domain: domain.veritas.com Name: username Password: You do not currently trust the server: test.domain.veritas.com, do you wish to trust it? (y/n): y Operation completed successfully.
Example 2 - The -WhoAmI option verifies the identity that you currently use within the Veritas Product Authentication and Authorization Service.
# bpnbat -WhoAmI Name: user name Domain: domain.veritas.com Issued by: /CN=broker/OU=root@eek.example.com/O=vx Expiry Date: Oct 27 20:57:43 2009 GMT Authentication method: NIS Operation completed successfully.
Example 3 - Add a computer to the computer identities list:
# bpnbat -AddMachine Machine Name: auto.domain.veritas.com Password: Operation completed successfully.
Next, it shows the computer identities list:
# bpnbat -ShowMachines auto.domain.veritas.com Operation completed successfully
Then it logs on a computer to a specified authentication broker:
# bpnbat -LoginMachine Does this machine use Dynamic Host Configuration Protocol (DHCP)? (y/n) n Authentication Broker: test.domain.veritas.com Authentication port[ Enter = default]: Name: auto.domain.veritas.com Password: Operation completed successfully.
Finally, you log into a computer to a specified authentication broker and a problem occurs:
If the user has a multi-NIC configuration or types the broker name incorrectly, a second prompt appears. It gives the user a second chance to enter the proper broker name. The following example assumes sleemanNB is a private NIC name. The public NIC name that Veritas Product Authentication and Authorization Service uses to build the authentication domain is sleeman.example.com. If a failure occurs with -loginmachine, the user has a second chance to enter an explicit primary host name for the authentication broker. (Failures include a bad computer name, wrong password, or incorrect broker name.) Refer to the following example:
# bpnbat -LoginMachine Does this machine use Dynamic Host Configuration Protocol (DHCP)? (y/n) n Authentication Broker: sleemanNB Authentication port[ Enter = default]: Machine Name: challenger Password: Primary host name of broker: sleeman.example.com Operation completed successfully.
Example 4 - Obtain a broker certificate without authenticating to a broker. It expects a broker (test.domain.veritas.com) and a port (0 for default)
# bpnbat -GetBrokerCert test.domain.veritas.com 0 Operation completed successfully.
Example 5 - Lists all the brokers that the user currently trusts
# bpnbat -ShowBrokerCerts Name: root Domain: root@test.domain.veritas.com Issued by: /CN=root/OU=root@test.domain.veritas.com/O=vx Expiry Date: Jun 12 20:45:19 2006 GMT Authentication method: Veritas Private Security Name: root Domain: root@auto.domain.veritas.com Issued by: /CN=root/OU=root@auto.domain.veritas.com/O=vx Expiry Date: Feb 17 19:05:39 2006 GMT Authentication method: Veritas Private Security Operation completed successfully.
Example 6 - The -RemoveBrokerCert option removes a broker when the user no longer wants to trust it. In the following example, an authentication broker is moved to a different corporate division.
# bpnbat -RemoveBrokerCert test.domain.veritas.com Operation completed successfully.
The user can now use the -ShowBrokerCerts option to display current certificates. The previously removed certificate is no longer displayed.
Example 7 - Show how to use an answer file to supply logon information for automated commands (cron, etc.).
For UNIX: The UNIX NIS domain name is location.example.com
, the user name in this domain is bgrable
, and the password is hello456
. The corresponding answer file for bpnbat -login must contain the following four lines:
NIS location.example.com bgrable hello456
If the answer file is located in /docs
and is called login.txt
, the bpnbat command executes as follows:
# bpnbat -login -info /docs/vslogin.txt
After the bpnbat -login command is run, commands like bpbackup can be run without authentication errors.
For Windows: The windows domain name is corporate, the user name in this domain is jsmith
, and the user password is hello123. The corresponding answer file for bpnbat -login has to contain the following four lines:
NT corporate jsmith hello123
If the answer file is located in /docs
and is called login.txt
, the bpnbat command executes as follows:
# bpnbat -login -info c:\docs\vslogin.txt
After the bpnbat -login command is run, commands like bpbackup can be run without authentication errors.
Example 8 - How to use the bpnbat -login command with the -LoginType parameter.
# bpnbat -login -LoginType AT Authentication Broker: server.domain.com Authentication port [0 is default]: 0 Authentication type (NIS, NISPLUS, WINDOWS, vx, unixpwd, ldap): unixpwd Domain: server.domain.com Login Name: root Password: Operation completed successfully.
# bpnbat -login -LoginType WEB Authentication Broker: server.domain.com Authentication port [0 is default]: 0 Authentication type (NIS, NISPLUS, WINDOWS, vx, unixpwd, ldap): unixpwd Domain: server.domain.com Login Name: root Password: Operation completed successfully.
