The IPA service record can store a Kerberos principal, an SSL certificate, or both. An IPA service can be managed directly from a machine, provided that machine has been given the correct permission. This is true even for machines other than the one the service is associated with. For example, requesting an SSL certificate using the host service principal credentials of the host. To manage a service using host credentials you need to kinit as the host: # kinit -kt /etc/krb5.keytab host/ipa.example.com@EXAMPLE.COM Adding an IPA service allows the associated service to request an SSL certificate or keytab, but this is performed as a separate step; they are not produced as a result of adding the service. Only the public aspect of a certificate is stored in a service record; the private key is not stored. EXAMPLES: Add a new IPA service: ipa service-add HTTP/web.example.com Allow a host to manage an IPA service certificate: ipa service-add-host --hosts=web.example.com HTTP/web.example.com ipa role-add-member --hosts=web.example.com certadmin Override a default list of supported PAC types for the service: ipa service-mod HTTP/web.example.com --pac-type=MS-PAC A typical use case where overriding the PAC type is needed is NFS. Currently the related code in the Linux kernel can only handle Kerberos tickets up to a maximal size. Since the PAC data can become quite large it is recommended to set --pac-type=NONE for NFS services. Delete an IPA service: ipa service-del HTTP/web.example.com Find all IPA services associated with a host: ipa service-find web.example.com Find all HTTP services: ipa service-find HTTP Disable the service Kerberos key and SSL certificate: ipa service-disable HTTP/web.example.com Request a certificate for an IPA service: ipa cert-request --principal=HTTP/web.example.com example.csr """) + _(""" Allow user to create a keytab: ipa service-allow-create-keytab HTTP/web.example.com --users=tuser1 """) + _(""" Generate and retrieve a keytab for an IPA service: ipa-getkeytab -s ipa.example.com -p HTTP/web.example.com -k /etc/httpd/httpd.keytab """) register = Registry() output_params = ( Flag('has_keytab', label=_('Keytab'), ), Str('managedby_host', label='Managed by', ), Str('ipaallowedtoperform_read_keys_user', label=_('Users allowed to retrieve keytab'), ), Str('ipaallowedtoperform_read_keys_group', label=_('Groups allowed to retrieve keytab'), ), Str('ipaallowedtoperform_read_keys_host', label=_('Hosts allowed to retrieve keytab'), ), Str('ipaallowedtoperform_read_keys_hostgroup', label=_('Host Groups allowed to retrieve keytab'), ), Str('ipaallowedtoperform_write_keys_user', label=_('Users allowed to create keytab'), ), Str('ipaallowedtoperform_write_keys_group', label=_('Groups allowed to create keytab'), ), Str('ipaallowedtoperform_write_keys_host', label=_('Hosts allowed to create keytab'), ), Str('ipaallowedtoperform_write_keys_hostgroup', label=_('Host Groups allowed to create keytab'), ), Str('ipaallowedtoperform_read_keys', label=_('Failed allowed to retrieve keytab'), ), Str('ipaallowedtoperform_write_keys', label=_('Failed allowed to create keytab'), ), ) ticket_flags_params = ( Bool('ipakrbrequirespreauth?', cli_name='requires_pre_auth', label=_('Requires pre-authentication'), doc=_('Pre-authentication is required for the service'), flags=['virtual_attribute', 'no_search'], ), Bool('ipakrbokasdelegate?', cli_name='ok_as_delegate', label=_('Trusted for delegation'), doc=_('Client credentials may be delegated to the service'), flags=['virtual_attribute', 'no_search'], ), ) _ticket_flags_map = { 'ipakrbrequirespreauth': 0x00000080, 'ipakrbokasdelegate': 0x00100000, } _ticket_flags_default = _ticket_flags_map['ipakrbrequirespreauth'] def validate_realm(ugettext, principal): """ Check that the principal's realm matches IPA realm if present """ realm = principal.realm if realm is not None and realm != api.env.realm: raise errors.RealmMismatch() def normalize_principal(value): """ Ensure that the name in the principal is lower-case.
