5.11.3. Creating a User With a Specific MLS Range

Follow these steps to create a new Linux user with a specific MLS range:

Add a new Linux user via the useradd command and map the new Linux user to an existing SELinux user (in this case, user_u):
```
~]# useradd -Z user_u john
```
Assign the newly-created Linux user a password:
```
~]# passwd john
```

Run the semanage login -l command to view the mapping between SELinux and Linux users. The output should be as follows:

Login Name                SELinux User              MLS/MCS Range

__default__               user_u                    s0
john                      user_u                    s0
root                      root                      s0-s15:c0.c1023
system_u                  system_u                  s0-s15:c0.c1023

Define a specific range for user john:

~]# semanage login --modify --seuser user_u --range s2:c100 john

Run the semanage login -l command to view the mapping between SELinux and Linux users. Note that the user john now has a specific MLS range defined:

Login Name                SELinux User              MLS/MCS Range

__default__               user_u                    s0
john                      user_u                    s2:c100
root                      root                      s0-s15:c0.c1023
system_u                  system_u                  s0-s15:c0.c1023

To correct the label on john's home directory (if needed), run the following command:
```
~]# chcon -R -l s2:c100 /home/john
```
