Hello,
I have a few services that I want to configure for kerberos authentication.
I use ansible for this.
So, I register the host in IPA, get the OTP, install the ipa-client, create the service
and then I need to go to the CLI to download the keytab.
I have this in my playbooks:
=====================
- name: Download the Keytab
block:
- name: Login to IPA Master
command: echo '{{ ipa_password }}' | kinit admin
no_log: true
- name: Download the keytab
command: >
ipa-getkeytab -s {{ ipa_master }} -p HTTP/{{ inventory_hostname }} -k
/etc/httpd/http_{{ inventory_hostname }}.keytab
=====================
This is failing with the error:
==============================
fatal: [server.example.com]: FAILED! => changed=true
cmd:
- ipa-getkeytab
- -s
- ipamaster.example.com
- -p
- HTTP/server.example.com
- -k
- /etc/httpd/http_server.example.com.keytab
delta: '0:00:00.005696'
end: '2020-05-11 12:43:59.935641'
msg: non-zero return code
rc: 6
start: '2020-05-11 12:43:59.929945'
stderr: Kerberos User Principal not found. Do you have a valid Credential Cache?
stderr_lines: <omitted>
stdout: ''
stdout_lines: <omitted>
==============================
However, if I login to the server, issue a ticket (kinit admin), logout and then re-run
the playbook succeeds!!!
Any idea how to fix this? Obviously I cannot login to each host and then run the
playbooks, this is not automation.
