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.
The following table lists the NBAC considerations.

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:
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:
Information about roles
Determine the roles in the configuration as follows:
NBAC license requirements
No license is required to turn on the access controls.
NBAC and KMS permissions
Typically when using NBAC and when 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. The solution is to grant the root and the administrator users NBU_Admin and KMS_Admin permissions manually.
Windows Server Failover Clustering (WSFC) error messages while unhooking shared security services from PBX
In WSFC 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 performed, NBAC needs to be reset back from PROHIBTED mode to REQUIRED mode.
Policy validation fails in NBAC mode (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.
The bpnbaz -setupmaster command fails with an error "Unable to contact Authorization Service"
If a user other than an Administrator tries to modify NetBackup security, the bpnbaz - setupmaster fails.
Only a user 'Administrator' who is a part of the Administrator's group has permissions to modify the NetBackup security and enable NBAC.
Failure of authentication broker configuration during installation.
Invalid domain name configuration of the system causes failure during configuration of authentication broker.
To correct this problem, use the bpnbaz -configureauth command to configure the authentication broker.
For information about the bpnbaz command, see the NetBackup Commands Reference Guide.
NetBackup GUI errors may occur if NBAC is enabled on a system that previously had Enhanced Auditing enabled.
When switching the NetBackup server from Enhanced Auditing to NBAC, make sure that all directories that are named after users are deleted in the following directory:
