Hi, I have manged to deployed 1 ipa master and 1 ipa client with success on centos 7.2 with freeipa v4.2. I also managed to create user and set sshd-rules to for ttester user and also successfully get krb ticket using *kinit ttes...@example.my*. I am trying to deploy password-less SSH login with kerberos using the following guide ( https://uz.sns.it/~enrico/wordpress/2014/03/password-less-ssh-login-with-kerberos/) -
