Freeipa Generate New Host Key
- Add, modify and delete an IPA host using IPA API
That looks more like a regular SSL/TLS guide. I was asking about interacting with FreeIPA (likely via certmonger, I think) specifically. If anyone has details on obtaining the default system cert (and especially the private key) and exporting/converting to PEMs, I'd greatly appreciate. # Generate a private key openssl genrsa -out postgresql.example.com.key 4096 # Add the host to FreeIPA, using the cname ipa host-add postgresql.example.com -force # Create a host principal for the service HTTP ipa service-add HTTP/abc955-xy.example.com # Create a principal for the service HTTP with the cname ipa service-add HTTP/postgresql.
| Parameter | Choices/Defaults | Comments |
|---|---|---|
| description - | ||
| force |
| Force host name even if not in DNS. |
| fqdn - / required | Can not be changed as it is the unique identifier. | |
| ip_address | Add the host to DNS with this IP address. | |
| ipa_host string | Default: | IP or hostname of IPA server. If the value is not specified in the task, the value of environment variable IPA_HOST will be used instead.If both the environment variable IPA_HOST and the value are not specified in the task, then DNS will be used to try to discover the FreeIPA server.The relevant entry needed in FreeIPA is the 'ipa-ca' entry. If neither the DNS entry, nor the environment IPA_HOST, nor the value are available in the task, then the default value will be used.Environment variable fallback mechanism is added in Ansible 2.5. |
| ipa_pass string / required | If the value is not specified in the task, the value of environment variable IPA_PASS will be used instead.Note that if the 'urllib_gssapi' library is available, it is possible to use GSSAPI to authenticate to FreeIPA. If the environment variable KRB5CCNAME is available, the module will use this kerberos credentials cache to authenticate to the FreeIPA server.If the environment variable KRB5_CLIENT_KTNAME is available, and KRB5CCNAME is not; the module will use this kerberos keytab to authenticate.If GSSAPI is not available, the usage of 'ipa_pass' is required. Environment variable fallback mechanism is added in Ansible 2.5. | |
| ipa_port integer | Default: | Port of FreeIPA / IPA server. If the value is not specified in the task, the value of environment variable IPA_PORT will be used instead.If both the environment variable IPA_PORT and the value are not specified in the task, then default value is set.Environment variable fallback mechanism is added in Ansible 2.5. |
| ipa_prot string |
| Protocol used by IPA server. If the value is not specified in the task, the value of environment variable IPA_PROT will be used instead.If both the environment variable IPA_PROT and the value are not specified in the task, then default value is set.Environment variable fallback mechanism is added in Ansible 2.5. |
| ipa_timeout integer | Default: 10 | Specifies idle timeout (in seconds) for the connection. For bulk operations, you may want to increase this in order to avoid timeout from IPA server. If the value is not specified in the task, the value of environment variable IPA_TIMEOUT will be used instead.If both the environment variable IPA_TIMEOUT and the value are not specified in the task, then default value is set. |
| ipa_user string | Default: | Administrative account used on IPA server. If the value is not specified in the task, the value of environment variable IPA_USER will be used instead.If both the environment variable IPA_USER and the value are not specified in the task, then default value is set.Environment variable fallback mechanism is added in Ansible 2.5. |
| mac_address - | If option is omitted MAC addresses will not be checked or changed. If an empty list is passed all assigned MAC addresses will be removed. MAC addresses that are already assigned but not passed will be removed. | |
| ns_hardware_platform | Host hardware platform (e.g. 'Lenovo T61') | |
| ns_host_location | Host location (e.g. 'Lab 2') | |
| ns_os_version | Host operating system and version (e.g. 'Fedora 9') | |
| random_password added in 2.5 |
| Generate a random password to be used in bulk enrollment |
| state - |
| State to ensure |
| update_dns boolean |
| If set 'True' with state as 'absent', then removes DNS records of the host managed by FreeIPA DNS.This option has no effect for states other than 'absent'. |
| user_certificate - | If option is omitted certificates will not be checked or changed. If an empty list is passed all assigned certificates will be removed. Certificates already assigned but not passed will be removed. | |
| validate_certs |
| If set to no, the SSL certificates will not be validated.This should only set to no used on personally controlled sites using self-signed certificates. |
Common return values are documented here, the following are the fields unique to this module:
| Key | Returned | Description |
|---|---|---|
| host dictionary | always | |
| host_diff | if check mode and a difference is found | List of options that differ and would be changed |

- 3How to test
- 4Expected Results
Verify FreeIPA's SSH public key management using realmd to join the current machine to a FreeIPA domain.
- If you have not already done so, run through the test case to join the domain.
Note: All examples below are executed either on server or client. The right place should be indicated by prompt:
Verify installation
First authenticate as admin:
Verify that the host entry of server.ipa.example.org has the correct SSH public keys set:
The same procedure can be used to verify host public keys of client.ipa.example.org.
Verify that DNS SSHFP records were updated correctly for client:
Public key management
Generate a SSH keypair and create new FreeIPA user with the public key set:
Verify that the user entry has the correct SSH public key set:
Generate another SSH keypair on client.ipa.example.org:
Add the public key to sshuser:
You can experiment further with ipa user-add, ipa user-mod, ipa host-add, ipa host-mod commands, all of them allow setting SSH public keys (in OpenSSH authorized_keys format, see man sshd) using the --sshpubkey option. Note that --sshpubkey overwrites the public keys of user or host with the new value(s), if you want to add or delete public keys, you have to use --addattr ipasshpubkey=.. or --delattr ipasshpubkey=.. instead.
Now that public keys for both hosts and user are set, you can try using ssh to log in remotely from server.ipa.example.org to client.ipa.example.org and vice-versa:
Both these commands should work without any warnings or errors and should NOT prompt for verification of host identity or password.
