Troubleshooting NBAC issues

The following table lists the issues and solutions that are related to NBAC:

Table: NBAC issues

Issue and Cause

Solution

A user directed backup or restore fails

A user-directed backup or restore fails with NBAC in the automated mode. The Backup, Archive, and Restore interface shows some errors in the Windows interface when NBAC is configured.

A backup or restore failure can happen when a NetBackup setup on a UNIX primary server is configured with NBAC and you try to use the Windows interface without first configuring the interface for such a setup. Another reason may be that there is an expired certificate in the home directory.

Configure the Windows interface to support the setup.

There should be at least one Microsoft Windows system that acts as an Authentication Broker to authenticate users from the Active Directory domain.

Refer to the TECH199281 for steps to configure the Windows interface to make use of existing users from Active Directory to manage or operate or use a NetBackup environment that is primarily on UNIX/Linux platforms.

After you correctly configure the setup run the bpnbat -logout command to log out from the setup before you restart the interface.

Authentication failure with error 116

The authentication fails with 'error 116-VxSS authentication' when you try to set up NBAC on a target host.

Check whether NBAC authentication is configured correctly and also if you have a valid usable credential for the target host.

Error when a non-admin user from the NBU_Operator group tries to use Access Management

A non-admin user is added to the NBU_Operator group. Read, Browse, and Configure permissions are assigned along with the permission to configure the Host Properties. However, when the user tries to open the Access Management utility, an error displays.

The users from the NBU_Operator group have limited permissions.

The user would require a different set of permissions to use the Access Management utility. For the required permissions, add the user to the NBU_Security_Admin group.

For more information about user groups:

See NetBackup default user groups.

The authorization file (auth.conf) functionality does not work in an NBAC-enabled environment. By default, the auth.conf file is supported by the Java interface in non-NBAC environments only.

For the auth.conf file to work in an NBAC-enabled environment, use the nbgetconfig and nbsetconfig commands to add the USE_AUTH_CONF_NBAC entry to the Windows registry or the bp.conf file on UNIX. The entry must be set to YES, as follows:

USE_AUTH_CONF_NBAC = YES

For more details about the auth.conf file, refer to the NetBackup Administrators Guide, Volume I.

Error when switching NetBackup server from Enhanced Auditing to NBAC

The NetBackup Administration Console creates user directories with user name as directory name, in netbackup/logs/user_ops. For Enhanced Auditing, these directories are used by NetBackup processes that run with root privileges. For NBAC, these directories are used by NetBackup processes that run without root privileges.

NetBackup GUI errors may occur in the following case:

  • The user directories that were created when Enhanced Auditing was enabled still exist when NBAC is enabled, and

  • Any of those users do not have root privileges.

Some examples of errors:

  • In the Backup, Archive, and Restore interface, no jobs appear on the Task Progress tab.

  • For a VMware VM restore, the pre-recovery check reports error 12.

  1. On each NetBackup server that the users log on to by means of the GUI, delete the user directories in the following directory:

    Windows: install_path\NetBackup\logs\user_ops

    UNIX, Linux: /usr/openv/netbackup/logs/user_ops

  2. When the directories are deleted, restart the NetBackup GUI.
