sssd_selinux(8) sssd SELinux Policy documentation sssd_selinux(8)NAMEsssd_selinux - Security Enhanced Linux Policy for the sssd processes
DESCRIPTION
Security-Enhanced Linux secures the sssd processes via flexible manda‐
tory access control.
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the sssd_t,
you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
sssd_t, you must turn on the allow_kerberos boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the sssd_t, you must
turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 1
FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file
type.
You can see the context of a file using the -Z option to ls
Policy governs the access confined processes have to these files.
SELinux sssd policy is very flexible allowing users to setup their sssd
processes in as secure a method as possible.
The following file types are defined for sssd:
sssd_exec_t
- Set files with the sssd_exec_t type, if you want to transition an
executable to the sssd_t domain.
sssd_initrc_exec_t
- Set files with the sssd_initrc_exec_t type, if you want to transition
an executable to the sssd_initrc_t domain.
sssd_public_t
- Set files with the sssd_public_t type, if you want to treat the files
as sssd public data.
Paths:
/var/lib/sss/mc(/.*)?, /var/lib/sss/pubconf(/.*)?
sssd_var_lib_t
- Set files with the sssd_var_lib_t type, if you want to store the sssd
files under the /var/lib directory.
sssd_var_log_t
- Set files with the sssd_var_log_t type, if you want to treat the data
as sssd var log data, usually stored under the /var/log directory.
sssd_var_run_t
- Set files with the sssd_var_run_t type, if you want to store the sssd
files under the /run directory.
Note: File context can be temporarily modified with the chcon command.
If you want to permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. You will need to use restorecon to apply the labels.
PROCESS TYPES
SELinux defines process types (domains) for each process running on the
system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux
sssd policy is very flexible allowing users to setup their sssd pro‐
cesses in as secure a method as possible.
The following process types are defined for sssd:
sssd_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process
type permissive. Permissive process types are not denied access by
SELinux. AVC messages will still be generated.
COMMANDS
semanage fcontext can also be used to manipulate default file context
mappings.
semanage permissive can also be used to manipulate whether or not a
process type is permissive.
semanage module can also be used to enable/disable/install/remove pol‐
icy modules.
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
