Access Control System
0.10.4
Salt maintains a standard system used to open granular control to non administrative users to execute Salt commands. The access control system has been applied to all systems used to configure access to non administrative control interfaces in Salt.
These interfaces include, the peer system, the
external auth system and the publisher acl
system.
The access control system mandated a standard configuration syntax used in all of the three aforementioned systems. While this adds functionality to the configuration in 0.10.4, it does not negate the old configuration.
Now specific functions can be opened up to specific minions from specific users in the case of external auth and publisher ACLs, and for specific minions in the case of the peer system.

When to Use Each Authentication System
publisher_acl is useful for allowing local system users
to run Salt commands without giving them root access. If you can log
into the Salt master directly, then publisher_acl allows
you to use Salt without root privileges. If the local system is
configured to authenticate against a remote system, like LDAP or Active
Directory, then publisher_acl will interact with the remote
system transparently.
external_auth is useful for salt-api or for
making your own scripts that use Salt's Python API. It can be used at
the CLI (with the -a flag) but it is more cumbersome as
there are more steps involved. The only time it is useful at the CLI is
when the local system is not configured to authenticate against
an external service but you still want Salt to authenticate
against an external service.
Examples
The access controls are manifested using matchers in these configurations:
publisher_acl:
fred:
- web\*:
- pkg.list_pkgs
- test.*
- apache.*In the above example, fred is able to send commands only to minions which match the specified glob target. This can be expanded to include other functions for other minions based on standard targets (all matchers are supported except the compound one).
external_auth:
pam:
dave:
- test.version
- mongo\*:
- network.*
- log\*:
- network.*
- pkg.*
- 'G@os:RedHat':
- kmod.*
steve:
- .*The above allows for all minions to be hit by test.version by dave, and adds a few functions that dave can execute on other minions. It also allows steve unrestricted access to salt commands.
Note
Functions are matched using regular expressions.
