 ## SSH Authentication with keys
 
-If you want to use ssh-keys you can also use different keys in `.ssh/config` per server with `IdentityFile ~/.ssh/id_enc_for_server`.
-
-**Note: If you are having trouble with your ssh-key being accepted. You need to check the selinux security policy. Because we use non standard home directories, which are not accepted by default.** Do that by running:
-
-```bash
-ls -ldZ ~/.ssh/
-drwx------. 2 monkey users system_u:object_r:ssh_home_t:s0 4.0K Aug 18 21:24 .ssh/
-
-ls -lZ ~/.ssh/
--rw-------. 1 monkey users unconfined_u:object_r:ssh_home_t:s0  1.3K Aug 17 10:58 authorized_keys
-```
-
-If you are not seeing `ssh_home_t` than you need to run `restorecon -Rv ~/.ssh/` which should update the security policy and allow for the SSH-Daemon to accept your keys.
-
 **Please add your ssh-keys via [IPA](IPA.md#add-ssh-key)**
