Security-Enhanced Linux secures the dirsrv processes via flexible mandatory access control.
The dirsrv processes execute with the dirsrv_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
For example:
ps -eZ | grep dirsrv_t
The dirsrv_t SELinux type can be entered via the dirsrv_exec_t file type.
The default entrypoint paths for the dirsrv_t domain are the following:
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux dirsrv policy is very flexible allowing users to setup their dirsrv processes in as secure a method as possible.
The following process types are defined for dirsrv:
dirsrv_t, dirsrv_snmp_t, dirsrvadmin_t, dirsrvadmin_unconfined_script_t, dirsrvadmin_script_t
Note: semanage permissive -a dirsrv_t can be used to make the process type dirsrv_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the authlogin_nsswitch_use_ldap boolean. Disabled by default.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
If you want to allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.
setsebool -P kerberos_enabled 1
If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 1
If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.
setsebool -P nscd_use_shm 1
The SELinux process type dirsrv_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.

You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux dirsrv policy is very flexible allowing users to setup their dirsrv processes in as secure a method as possible.
EQUIVALENCE DIRECTORIES
dirsrv policy stores data with multiple different file context types under the /var/log/dirsrv directory. If you would like to store the data in a different directory you can use the semanage command to create an equivalence mapping. If you wanted to store this data under the /srv dirctory you would execute the following command:
semanage fcontext -a -e /var/log/dirsrv /srv/dirsrv
restorecon -R -v /srv/dirsrv
STANDARD FILE CONTEXT
SELinux defines the file context types for the dirsrv, if you wanted to store files with these types in a diffent paths, you need to execute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t dirsrvadmin_ra_content_t '/srv/mydirsrv_content(/.*)?'
restorecon -R -v /srv/mydirsrv_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for dirsrv:
dirsrv_config_t
- Set files with the dirsrv_config_t type, if you want to treat the files as dirsrv configuration data, usually stored under the /etc directory.
dirsrv_exec_t
- Set files with the dirsrv_exec_t type, if you want to transition an executable to the dirsrv_t domain.
dirsrv_share_t
- Set files with the dirsrv_share_t type, if you want to treat the files as dirsrv share data.
dirsrv_snmp_exec_t
- Set files with the dirsrv_snmp_exec_t type, if you want to transition an executable to the dirsrv_snmp_t domain.
dirsrv_snmp_var_log_t
- Set files with the dirsrv_snmp_var_log_t type, if you want to treat the data as dirsrv snmp var log data, usually stored under the /var/log directory.
dirsrv_snmp_var_run_t
- Set files with the dirsrv_snmp_var_run_t type, if you want to store the dirsrv snmp files under the /run or /var/run directory.

dirsrvadmin_content_t
- Set files with the dirsrvadmin_content_t type, if you want to treat the files as dirsrvadmin content.
dirsrvadmin_exec_t
- Set files with the dirsrvadmin_exec_t type, if you want to transition an executable to the dirsrvadmin_t domain.

- Set files with the dirsrvadmin_unit_file_t type, if you want to treat the files as dirsrvadmin unit content.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
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 policy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
