About RBAC bootstrapping

RBAC Bootstrapping lets you assign role-based access control (RBAC) permissions to a user or a user group during NetBackup installation or upgrade on Linux platforms. The Linux installer uses the bpnbaz -AddRBACPrincipal command to grant the Administrator role permissions to the user or the user group that you specify in the /tmp/NBInstallAnswer.conf file.

Note:

RBAC bootstrapping provides access to all objects for the specified user or user group, even if previously the user or the user group had restricted access to certain objects. For example, the existing user Tester1 was assigned the Default VMware Administrator role. If Tester 1 is specified for RBAC bootstrapping, Tester1 is assigned the Administrator role.

After installation or upgrade, you can run the bpnbaz -AddRBACPrincipal command standalone on both Windows and Linux platforms to assign RBAC permissions. The command is available only on the primary server. For more information about this command, see the NetBackup Commands Reference Guide.

RBAC Bootstrapping during installation and upgrades on Linux platforms:

Use the answer file template NBInstallAnswer-primary.template available in the install package to create the /tmp/NBInstallAnswer.conf file. In that file, add the following entries before you run the installation or upgrade:

RBAC_DOMAIN_TYPE = domain_type

RBAC_DOMAIN_NAME = domain_name

RBAC_PRINCIPAL_TYPE = USER | USERGROUP

RBAC_PRINCIPAL_NAME = principal_name

Be aware that RBAC_DOMAIN_TYPE supports the values shown: NT, VX, UNIXPWD, LDAP.

Note:

Additional information about the RBAC_* options is available.

See About the NetBackup answer file.

RBAC bootstrapping is not performed if all the entries are empty or missing. In this case, the message Answer file did not contain any RBAC entries is posted in the install trace file. The install process always continues whether the RBAC bootstrapping is successful or not. The audit records are created under the SEC_CONFIG category.

If RBAC bootstrapping is successful, the installer displays the following message:

Successfully configured the RBAC permissions for principal_name.

The installer also displays this message if the user or the user group already exists with the Administrator RBAC role.

If one or more RBAC entries exist in the answer file, but a required answer file entry is missing, the installer displays the following message:

Warning: Unable to configure the RBAC permissions. One or more required fields are missing in /tmp/NBInstallAnswer.conf.

If there are other issues with the RBAC Bootstrapping, the installer displays the following message:

Warning: Failed to configure the RBAC permissions for principal_name. Refer to logs in /usr/openv/netbackup/logs/admin for more information.

If RBAC bootstrapping is successful but auditing fails, the install displays the following message:

Successfully configured the RBAC permissions for 
user_or_usergroup_name.
WARNING: Auditing of this operation failed.
Refer to logs in /usr/openv/netbackup/logs/admin for more information.

After the installation or upgrade completes, the specified user or user group is assigned the Administrator role with its corresponding RBAC access permissions. The user can then access APIs and the Web UI.
