+                          of this License, Derivative Works shall not include works that remain
+                          separable from, or merely link (or bind by name) to the interfaces of,

+                          subsequently incorporated within the Work.
+
+                       2. Grant of Copyright License. Subject to the terms and conditions of
+                          this License, each Contributor hereby grants to You a perpetual,
+                          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+                          copyright license to reproduce, prepare Derivative Works of,
+                          publicly display, publicly perform, sublicense, and distribute the
+                          Work and such Derivative Works in Source or Object form.
+
+                       3. Grant of Patent License. Subject to the terms and conditions of
+                          this License, each Contributor hereby grants to You a perpetual,
+                          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+                          (except as stated in this section) patent license to make, have made,
+                          use, offer to sell, sell, import, and otherwise transfer the Work,
+                          where such license applies only to those patent claims licensable
+                          by such Contributor that are necessarily infringed by their
+                          Contribution(s) alone or by combination of their Contribution(s)
+                          with the Work to which such Contribution(s) was submitted. If You
+                          institute patent litigation against any entity (including a
+                          cross-claim or counterclaim in a lawsuit) alleging that the Work
+                          or a Contribution incorporated within the Work constitutes direct
+                          or contributory patent infringement, then any patent licenses
+                          granted to You under this License for that Work shall terminate
+                          as of the date such litigation is filed.
+
+                       4. Redistribution. You may reproduce and distribute copies of the
+                          Work or Derivative Works thereof in any medium, with or without
+                          modifications, and in Source or Object form, provided that You
+                          meet the following conditions:
+
+                          (a) You must give any other recipients of the Work or
+                              Derivative Works a copy of this License; and
+
+                          (b) You must cause any modified files to carry prominent notices
+                              stating that You changed the files; and
+
+                          (c) You must retain, in the Source form of any Derivative Works
+                              that You distribute, all copyright, patent, trademark, and
+                              attribution notices from the Source form of the Work,
+                              excluding those notices that do not pertain to any part of
+                              the Derivative Works; and
+
+                          (d) If the Work includes a "NOTICE" text file as part of its
+                              distribution, then any Derivative Works that You distribute must
+                              include a readable copy of the attribution notices contained
+                              within such NOTICE file, excluding those notices that do not
+                              pertain to any part of the Derivative Works, in at least one
+                              of the following places: within a NOTICE text file distributed
+                              as part of the Derivative Works; within the Source form or
+                              documentation, if provided along with the Derivative Works; or,
+                              within a display generated by the Derivative Works, if and
+                              wherever such third-party notices normally appear. The contents
+                              of the NOTICE file are for informational purposes only and
+                              do not modify the License. You may add Your own attribution
+                              notices within Derivative Works that You distribute, alongside
+                              or as an addendum to the NOTICE text from the Work, provided
+                              that such additional attribution notices cannot be construed
+                              as modifying the License.
+
+                          You may add Your own copyright statement to Your modifications and
+                          may provide additional or different license terms and conditions
+                          for use, reproduction, or distribution of Your modifications, or
+                          for any such Derivative Works as a whole, provided Your use,
+                          reproduction, and distribution of the Work otherwise complies with
+                          the conditions stated in this License.
+
+                       5. Submission of Contributions. Unless You explicitly state otherwise,
+                          any Contribution intentionally submitted for inclusion in the Work
+                          by You to the Licensor shall be under the terms and conditions of
+                          this License, without any additional terms or conditions.
+                          Notwithstanding the above, nothing herein shall supersede or modify
+                          the terms of any separate license agreement you may have executed
+                          with Licensor regarding such Contributions.
+
+                       6. Trademarks. This License does not grant permission to use the trade
+                          names, trademarks, service marks, or product names of the Licensor,
+                          except as required for reasonable and customary use in describing the
+                          origin of the Work and reproducing the content of the NOTICE file.
+
+                       7. Disclaimer of Warranty. Unless required by applicable law or
+                          agreed to in writing, Licensor provides the Work (and each
+                          Contributor provides its Contributions) on an "AS IS" BASIS,
+                          WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+                          implied, including, without limitation, any warranties or conditions
+                          of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+                          PARTICULAR PURPOSE. You are solely responsible for determining the
+                          appropriateness of using or redistributing the Work and assume any
+                          risks associated with Your exercise of permissions under this License.
+
+                       8. Limitation of Liability. In no event and under no legal theory,
+                          whether in tort (including negligence), contract, or otherwise,
+                          unless required by applicable law (such as deliberate and grossly
+                          negligent acts) or agreed to in writing, shall any Contributor be
+                          liable to You for damages, including any direct, indirect, special,
+                          incidental, or consequential damages of any character arising as a
+                          result of this License or out of the use or inability to use the
+                          Work (including but not limited to damages for loss of goodwill,
+                          work stoppage, computer failure or malfunction, or any and all
+                          other commercial damages or losses), even if such Contributor
+                          has been advised of the possibility of such damages.
+
+                       9. Accepting Warranty or Additional Liability. While redistributing
+                          the Work or Derivative Works thereof, You may choose to offer,
+                          and charge a fee for, acceptance of support, warranty, indemnity,
+                          or other liability obligations and/or rights consistent with this
+                          License. However, in accepting such obligations, You may act only
+                          on Your own behalf and on Your sole responsibility, not on behalf
+                          of any other Contributor, and only if You agree to indemnify,
+                          defend, and hold each Contributor harmless for any liability
+                          incurred by, or claims asserted against, such Contributor by reason
+                          of your accepting any such warranty or additional liability.
+
+                       END OF TERMS AND CONDITIONS

+                       APPENDIX: How to apply the Apache License to your work.

+The authkey is generated based on the following conditions:
+- Is the node a founder node, this is checked by looking at
+the attribute `node[:pacemaker][:founder]`
+- Is there another founder node within the same cluster and
+whether that particular node has already generated the authkey
+- Does the current node have the authkey set as the attribute
+`node[:corosync][:authkey]`
+
+Clients then use the `node[:corosync][:authkey]` attribute for
+for cluster communication.
