smitacl.user File

Purpose

Contains the user access control list (ACL) definitions for the System Manamgement Interface Tool (SMIT). This system file only applies to AIX 4.2.1 and later.

Description

The /etc/security/smitacl.user file contains the ACL definitions for SMIT. This is an ASCII file that contains a stanza for each system user. Each stanza is identified by a user name followed by a : (colon) and contains attributes in the form Attribute=Value. Each attribute pair ends with a newline character as does each stanza.

The file supports a default stanza. If an attribute is not defined, either the default stanza or the default value for the attribute is used.

A stanza contains the following attributes:

Attribute	Description
screens	Describes the list of SMIT screens for the user. (It is of the type SEC_LIST.) Examples include: screens = * # Permit all screen access. screens = !* # Deny all screen access. screens = # Allows no specific screens # (screens can be added on a per user basis) screens = user,group,!tcpip # Allow user & group # screens, but not # tcpip screen
funcmode	Describes if the role database and/or SMIT ACL database should be used to determine accessibility. It also describes how to combine the screens data from the two databases. (It is of the type SEC_CHAR.) Examples include: funcmode = roles+acl # Use both roles and SMIT ACL # databases. funcmode = roles # Use only the roles database. funcmode = acl # Use only the SMIT ACL # database. The defined values for funcmode are: roles Only the screen values from the roles database are used. acl Only the screen values from the SMIT ACL database are used. roles+acl The screen values from both the roles and the SMIT ACL databases are used.

Attribute

Description

screens

Describes the list of SMIT screens for the user. (It is of the type SEC_LIST.) Examples include:

screens = *                    # Permit all screen access.
screens = !*                   # Deny all screen access.
screens =                      # Allows no specific screens
                               # (screens can be added on a per user basis)
screens = user,group,!tcpip    # Allow user & group
                               # screens, but not
                               # tcpip screen

funcmode

Describes if the role database and/or SMIT ACL database should be used to determine accessibility. It also describes how to combine the screens data from the two databases. (It is of the type SEC_CHAR.) Examples include:

funcmode = roles+acl   # Use both roles and SMIT ACL # databases.
funcmode = roles       # Use only the roles database.
funcmode = acl         # Use only the SMIT ACL # database.

The defined values for funcmode are:

roles: Only the screen values from the roles database are used.
acl: Only the screen values from the SMIT ACL database are used.
roles+acl: The screen values from both the roles and the SMIT ACL databases are used.

For a typical stanza, see the "Examples" section .

Security

Access Control: This file grants read and write access to the root user, and read access to members of the security group.

Examples

A typical stanza looks like the following example for the username user:
```
username:
        screens = *
        funcmode = roles+acl 
```
To allow the mksysb screen only for user groupuser, add the following stanza:
```
default:
        screen = *
        screens = mksysb
```
