SSSD-SIMPLE(5) File Formats and Conventions SSSD-SIMPLE(5)
NAME
sssd-simple - the configuration file for SSSD's 'simple' access-control
provider
DESCRIPTION
This manual page describes the configuration of the simple
access-control provider for sssd(8). For a detailed syntax reference,
refer to the “FILE FORMAT” section of the sssd.conf(5) manual page.
The simple access provider grants or denies access based on an access
or deny list of user or group names. The following rules apply:
• If all lists are empty, access is granted
• If any list is provided, the order of evaluation is allow,deny.
This means that any matching deny rule will supersede any matched
allow rule.
• If either or both "allow" lists are provided, all users are denied
unless they appear in the list.
• If only "deny" lists are provided, all users are granted access
unless they appear in the list.
CONFIGURATION OPTIONS
Refer to the section “DOMAIN SECTIONS” of the sssd.conf(5) manual page
for details on the configuration of an SSSD domain.
simple_allow_users (string)
Comma separated list of users who are allowed to log in.
simple_deny_users (string)
Comma separated list of users who are explicitly denied access.
simple_allow_groups (string)
Comma separated list of groups that are allowed to log in. This
applies only to groups within this SSSD domain. Local groups are
not evaluated.
simple_deny_groups (string)
Comma separated list of groups that are explicitly denied access.
This applies only to groups within this SSSD domain. Local groups
are not evaluated.
Specifying no values for any of the lists is equivalent to skipping it
entirely. Beware of this while generating parameters for the simple
provider using automated scripts.
Please note that it is an configuration error if both,
simple_allow_users and simple_deny_users, are defined.
EXAMPLE
The following example assumes that SSSD is correctly configured and
example.com is one of the domains in the [sssd] section. This examples
shows only the simple access provider-specific options.
[domain/example.com]
access_provider = simple
simple_allow_users = user1, user2
NOTES
The complete group membership hierarchy is resolved before the access
check, thus even nested groups can be included in the access lists.
Please be aware that the “ldap_group_nesting_level” option may impact
the results and should be set to a sufficient value. (sssd-ldap(5))
option.
