About using NetBackup Access Control (NBAC)
The NetBackup Access Control (NBAC) is the role-based access control that is used for master servers, media servers, and clients. NBAC can be used in situations where you want to:
Use a set of permissions for different levels of administrators for an application. A backup application can have operators (perhaps load and unload tapes). It can have local administrators (manage the application within one facility). It can also have overall administrators who may have responsibility for multiple sites and determine backup policy. Note that this feature is very useful in preventing user errors. If junior level administrators are restricted from certain operations, they are prevented from making inadvertent mistakes.
Separate administrators so that root permission to the system is not required to administer the system. You can then separate the administrators for the systems themselves from the ones who administer the applications.
It has been found that NBAC running on NetBackup 6.5 (AZ version 188.8.131.52) cannot be upgraded to NetBackup 7.5. It is important that you upgrade to AZ version 6.5.4 (184.108.40.206) before the NBAC upgrade from NetBackup 6.5 to NetBackup 7.5 is successful.
The following table lists the NBAC considerations.

Description or resolution
Prerequisites before you configure NBAC
This prerequisites list can help you before you start to configure NBAC. These items ensure an easier installation. The following list contains the information for this installation:
User name or password for master server (root or administrator permission).
Name of master server
Name of all media servers that are connected to the master server
Name of all clients to be backed up
Host name or IP address
Host names should be resolvable to a valid IP address.
Use the ping or traceroute command as one of the tools to ensure that you can see the hosts. Using these commands ensures that you have not configured a firewall or other obstruction to block access.
Determine if the master server, media server, or client is to be upgraded
Determine if the master server, media server, or client is to be upgraded as follows:
Some features are provided by upgrading master servers, some by media servers, and some from upgrading clients.
NetBackup works with a higher revision master server and lower revision clients and media servers.
Feature content determines what is deployed.
Deployment can be step wise if required.
Information about roles
Determine the roles in the configuration as follows:
NBAC license key requirements
No license is required to turn on the access controls.
NBAC and KMS permissions
Typically when using NBAC and the Setupmaster command is run, the NetBackup related group
permissions (for example, NBU_Admin and KMS_Admin) are created. The default root and administrator
users are also added to those groups. In some cases the root and administrator users are not added to the KMS group when NetBackup is upgraded from 6.5.x to 7.0 or from 7.0 to 7.0.1. The solution is to grant the root and administrator users NBU_Admin and KMS_Admin permissions manually.
MSCS Error messages while unhooking shared security services from PBX
In MSCS environments running the bpnbaz -UnhookSharedSecSvcsWithPBX <virtualhostname> command can trigger error messages. However the shared Authentication and Authorization services are successfully unhooked from PBX and the errors can be ignored.
Possible cluster node errors
In a clustered environment when the command bpnbaz -setupmaster is run in the context of
local Administrator the AUTHENTICATION_DOMAIN entries may not contain the other cluster node entries. In such case these entries must be manually added from Host
Properties into the
Catalog recovery fails when NBAC is set to REQUIRED mode
If NBAC is running in REQUIRED mode and a catalog recovery was preformed, NBAC needs to be reset back from PROHIBTED mode to REQUIRED mode.
Policy validation fails in NBAC mode (i.e. USE_VXSS = REQUIRED)
Back up, restore, and verification of policy for snapshot can fail in NBAC enabled
mode if one of the following has been done.
