8 Sun StorageTek SAM Archive Configuration and Administration Guide • Version 4, Update 6, 04/07

To assign bobsmith privileges only for staging and restoring file systems (privilege

level com.sun.netstorage.fsmgr.operator.file) and exporting, importing,

and assigning VSNs (privilege level com.sun.netstorage.operator.media),

add the following line to the /etc/user_attr file:

bobsmith::::auths=com.sun.netstorage.fsmgr.operator.file,

com.sun.netstorage.fsmgr.operator.media

Creating an Account for Multiple Users

You can create a generic File System Manager account that can be used by multiple

users, and then add a role with privileges that only some of those users can access.

1. Use the useradd and passwd commands to add the account.

For example, to add a user account called guest for multiple users, type the

following:

# /usr/sbin/useradd guest

# /usr/bin/passwd guest

2. Use the roleadd and passwd commands to add the role.

To create a role called admin with special privileges within the guest account, type

the following:

# /usr/sbin/roleadd admin

# /usr/bin/passwd admin

3. Specify the privilege levels in the /etc/user_attr file.

To assign the admin role privileges to restore and stage file systems, add the

following lines to the /etc/user_attr file:

admin::::auths=com.sun.netstorage.fsmgr.operator.file

guest::::type=normal;roles=admin

In this example, when a user logs in as guest, File System Manager prompts the

user to select either No Role or Admin. If users know the Admin role password, they

can select Admin, enter the Admin password, and have privileges to restore and

stage file systems. All other users must select No Role and have read-only privileges.

Because multiple users with the same privilege level can be logged in to the software

concurrently, there is a risk of one user’s changes overwriting another user’s

previous changes. To prevent this, develop policies about who can make changes

and how to notify others.
