NAME¶

semanage-user - SELinux Policy Management SELinux User mapping tool

SYNOPSIS¶

semanage user [-h] [-n] [-N] [-S STORE] [ --add ( -L LEVEL -R ROLES -r RANGE -s SEUSER selinux_name) | --delete selinux_name | --deleteall | --extract | --list [-C] | --modify ( -L LEVEL -R ROLES -r RANGE -s SEUSER selinux_name ) ]

DESCRIPTION¶

semanage is used to configure certain elements of SELinux policy without requiring modification to or recompilation from policy sources. semanage user controls the mapping between an SELinux User and the roles and MLS/MCS levels.

OPTIONS¶

-h, --help

show this help message and exit

-n, --noheading

Do not print heading when listing the specified object type

-N, --noreload

Do not reload policy after commit

-S STORE, --store STORE

Select an alternate SELinux Policy Store to manage

-C, --locallist

List local customizations

-a, --add

Add a record of the specified object type

-d, --delete

Delete a record of the specified object type

-m, --modify

Modify a record of the specified object type

-l, --list

List records of the specified object type

-E, --extract

Extract customizable commands, for use within a transaction

-D, --deleteall

Remove all local customizations

-L LEVEL, --level LEVEL

Default SELinux Level for SELinux user, s0 Default. (MLS/MCS Systems only)

-r RANGE, --range RANGE

MLS/MCS Security Range (MLS/MCS Systems only) SELinux Range for SELinux login mapping defaults to the SELinux user record range. SELinux Range for SELinux user defaults to s0.

-R [ROLES], --roles [ROLES]

SELinux Roles. You must enclose multiple roles within quotes, separate by spaces. Or specify -R multiple times.

EXAMPLE¶

List SELinux users
# semanage user -l
Modify groups for staff_u user
# semanage user -m -R "system_r unconfined_r staff_r" staff_u
Add level for TopSecret Users
# semanage user -a -R "staff_r" -rs0-TopSecret topsecret_u

NOTES¶

SELinux users defined in the policy cannot be removed or directly altered. When the -m switch is used on such a user, semanage creates a local SELinux user of the same name, which overrides the original SELinux user.

As long as a login entry exists that links local SELinux user to a Linux user, given local SELinux user cannot be removed (even if it represents local modification of a SELinux user defined in policy). In case you want to remove local modification of a SELinux user, you need to remove any related login mapping first. Follow these steps:

1) Remove all login entries concerning the SELinux user.


   To list local customizations of login entries execute:


   # semanage login -l -C


   or for semanage command form:


   # semanage login --extract
2) Remove the SELinux user
3) Optionally reintroduce removed login entries
