courier_authdaemon_seliSELinux Policy courier_autcourier_authdaemon_selinux(8)

NAME
       courier_authdaemon_selinux  -  Security	Enhanced  Linux Policy for the
       courier_authdaemon processes

DESCRIPTION
       Security-Enhanced Linux secures the  courier_authdaemon	processes  via
       flexible mandatory access control.

       The  courier_authdaemon processes execute with the courier_authdaemon_t
       SELinux type. You can check if you have these processes running by exe‐
       cuting the ps command with the -Z qualifier.

       For example:

       ps -eZ | grep courier_authdaemon_t

ENTRYPOINTS
       The   courier_authdaemon_t   SELinux   type  can	 be  entered  via  the
       courier_authdaemon_exec_t file type.

       The default entrypoint paths for the  courier_authdaemon_t  domain  are
       the following:

       /usr/lib/courier/authlib/.*, /usr/sbin/authdaemond

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
       courier_authdaemon  policy  is  very  flexible  allowing users to setup
       their courier_authdaemon processes in as secure a method as possible.

       The following process types are defined for courier_authdaemon:

       courier_authdaemon_t

       Note: semanage permissive -a courier_authdaemon_t can be used  to  make
       the process type courier_authdaemon_t permissive. SELinux does not deny
       access to permissive process types, but the AVC (SELinux denials)  mes‐
       sages are still generated.

BOOLEANS
       SELinux	 policy	 is  customizable  based  on  least  access  required.
       courier_authdaemon policy is extremely flexible and has	several	 bool‐
       eans that allow you to manipulate the policy and run courier_authdaemon
       with the tightest access possible.

       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 authlo‐
       gin_nsswitch_use_ldap boolean. Disabled by default.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow all daemons to write corefiles to /, you must turn
       on the daemons_dump_core boolean. Disabled by default.

       setsebool -P daemons_dump_core 1

       If  you	want  to enable cluster mode for daemons, you must turn on the
       daemons_enable_cluster_mode boolean. Enabled by default.

       setsebool -P daemons_enable_cluster_mode 1

       If you want to allow all daemons to use tcp wrappers, you must turn  on
       the daemons_use_tcp_wrapper boolean. Disabled by default.

       setsebool -P daemons_use_tcp_wrapper 1

       If  you	want to allow all daemons the ability to read/write terminals,
       you must turn on the daemons_use_tty boolean. Disabled by default.

       setsebool -P daemons_use_tty 1

       If you want to deny any process from ptracing or	 debugging  any	 other
       processes,  you	must  turn  on	the  deny_ptrace  boolean.  Enabled by
       default.

       setsebool -P deny_ptrace 1

       If you want to allow all domains to use other domains file descriptors,
       you must turn on the domain_fd_use boolean. Enabled by default.

       setsebool -P domain_fd_use 1

       If  you	want to allow all domains to have the kernel load modules, you
       must  turn  on  the  domain_kernel_load_modules	boolean.  Disabled  by
       default.

       setsebool -P domain_kernel_load_modules 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 enable reading of urandom for all domains, you must turn
       on the global_ssp boolean. Disabled by default.

       setsebool -P global_ssp 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. Disabled by default.

       setsebool -P nscd_use_shm 1

NSSWITCH DOMAIN
       If you want to allow users to resolve user passwd entries directly from
       ldap  rather then using a sssd server for the courier_authdaemon_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
       courier_authdaemon_t, you must turn on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

MANAGED FILES
       The  SELinux process type courier_authdaemon_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.

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 courier_authdaemon policy is very flexible  allowing  users  to
       setup  their courier_authdaemon processes in as secure a method as pos‐
       sible.

       STANDARD FILE CONTEXT

       SELinux defines the file context types for the  courier_authdaemon,  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 courier_authdaemon_exec_t '/srv/courier_auth‐
       daemon/content(/.*)?'
       restorecon -R -v /srv/mycourier_authdaemon_content

       Note: SELinux often uses regular expressions  to	 specify  labels  that
       match multiple files.

       The following file types are defined for courier_authdaemon:

       courier_authdaemon_exec_t

       -  Set  files  with  the courier_authdaemon_exec_t type, if you want to
       transition an executable to the courier_authdaemon_t domain.

       Paths:
	    /usr/lib/courier/authlib/.*, /usr/sbin/authdaemond

       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 data‐
       base.  You will need to use restorecon to apply the labels.

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.

       semanage boolean can also be used to manipulate the booleans

       system-config-selinux is a GUI tool available to customize SELinux pol‐
       icy settings.
