The following task map describes procedures to change device authorizations at your site.
If no authorization is specified at the time a device is created, by default, all users can use the device. If an authorization is specified, then, by default, only authorized users can use the device.
To prevent all access to an allocatable device without using authorizations, see Example 23-1.
You must be in the Security Administrator role in the global zone.
Use the reverse-order Internet domain name of your organization followed by optional additional arbitrary components, such as the name of your company. Separate components by dots. End heading names with a dot.
Add the authorizations, one authorization per line. The lines are split for display purposes. The authorizations include grant authorizations that enable administrators to assign the new authorizations.
domain-suffix.domain-prefix.grant:::Grant All Company Authorizations:: help=CompanyGrant.html domain-suffix.domain-prefix.grant.device:::Grant Company Device Authorizations:: help=CompanyGrantDevice.html domain-suffix.domain-prefix.device.allocate.tape:::Allocate Tape Device:: help=CompanyTapeAllocate.html domain-suffix.domain-prefix.device.allocate.floppy:::Allocate Floppy Device:: help=CompanyFloppyAllocate.html
For information, see the ldapaddent(1M) man page.
Add the new authorizations to the list of required authorizations in the Device Manager. For the procedure, see How to Add Site-Specific Authorizations to a Device in Trusted Extensions.
Example 23-2 Creating Fine-Grained Device Authorizations
A security administrator for NewCo needs to construct fine-grained device authorizations for the company.
First, the administrator writes the following help files, and places the files in the /usr/lib/help/auths/locale/C directory:
Newco.html NewcoGrant.html NewcoGrantDevice.html NewcoTapeAllocate.html NewcoFloppyAllocate.html
Next, the administrator adds a header for all of the authorizations for newco.com in the auth_attr file.
# auth_attr file com.newco.:::NewCo Header::help=Newco.html
Next, the administrator adds authorization entries to the file:
com.newco.grant:::Grant All NewCo Authorizations:: help=NewcoGrant.html com.newco.grant.device:::Grant NewCo Device Authorizations:: help=NewcoGrantDevice.html com.newco.device.allocate.tape:::Allocate Tape Device:: help=NewcoTapeAllocate.html com.newco.device.allocate.floppy:::Allocate Floppy Device:: help=NewcoFloppyAllocate.html
The lines are split for display purposes.
The auth_attr entries create the following authorizations:
An authorization to grant all NewCo's authorizations
An authorization to grant NewCo's device authorizations
An authorization to allocate a tape drive
An authorization to allocate a diskette drive
Example 23-3 Creating Trusted Path and Non-Trusted Path Authorizations
By default, the Allocate Devices authorization enables allocation from the trusted path and from outside the trusted path.
In the following example, site security policy requires restricting remote CD-ROM allocation. The security administrator creates the com.someco.device.cdrom.local authorization. This authorization is for CD-ROM drives that are allocated with the trusted path. The com.someco.device.cdrom.remote authorization is for those few users who are allowed to allocate a CD-ROM drive outside the trusted path.
The security administrator creates the help files, adds the authorizations to the auth_attr database, adds the authorizations to the devices, and then places the authorizations in rights profiles. The profiles are assigned to users who are allowed to allocate devices.
The following are the auth_attr database entries:
com.someco.:::SomeCo Header::help=Someco.html com.someco.grant:::Grant All SomeCo Authorizations:: help=SomecoGrant.html com.someco.grant.device:::Grant SomeCo Device Authorizations:: help=SomecoGrantDevice.html com.someco.device.cdrom.local:::Allocate Local CD-ROM Device:: help=SomecoCDAllocateLocal.html com.someco.device.cdrom.remote:::Allocate Remote CD-ROM Device:: help=SomecoCDAllocateRemote.html
The following is the Device Manager assignment:
The Trusted Path enables authorized users to use the Device Manager when allocating the local CD-ROM drive.
Device Name: cdrom_0 For Allocations From: Trusted Path Allocatable By: Authorized Users Authorizations: com.someco.device.cdrom.local
The Non-Trusted Path enables users to allocate a device remotely by using the allocate command.
Device Name: cdrom_0 For Allocations From: Non-Trusted Path Allocatable By: Authorized Users Authorizations: com.someco.device.cdrom.remote
The following are the rights profile entries:
# Local Allocator profile com.someco.device.cdrom.local # Remote Allocator profile com.someco.device.cdrom.remote
The following are the rights profiles for authorized users:
# List of profiles for regular authorized user Local Allocator Profile ... # List of profiles for role or authorized user Remote Allocator Profile ...
You must be in the Security Administrator role, or in a role that includes the Configure Device Attributes authorization. You must have already created site-specific authorizations, as described in How to Create New Device Authorizations.
The new authorizations are displayed in the Not Required list.
The Allocate Device authorization enables users to allocate a device. The Allocate Device authorization, and the Revoke or Reclaim Device authorization, are appropriate for administrative roles.
You must be in the Security Administrator role in the global zone.
If the existing profiles are not appropriate, the security administrator can create a new profile. For an example, see How to Create a Rights Profile for Convenient Authorizations.
For assistance, see the online help. For the step-by-step procedure, see How to Change the RBAC Properties of a User in System Administration Guide: Security Services.

Example 23-4 Assigning New Device Authorizations
In this example, the security administrator configures the new device authorizations for the system and assigns the rights profile with the new authorizations to trustworthy users. The security administrator does the following:
Creates new device authorizations, as in How to Create New Device Authorizations
In the Device Manager, adds the new device authorizations to the tape and diskette drives
Places the new authorizations in the rights profile, NewCo Allocation
Adds the NewCo Allocation rights profile to the profiles of users and roles who are authorized to allocate tape and diskette drives
Authorized users and roles can now use the tape drives and diskette drives on this system.
