+# no-same-owner
+
+This rule checks that the owner and group do not transfer across hosts.
+
+In many cases the owner and group on remote hosts do not match the owner and group assigned to source files.
+Preserving the owner and group during transfer can result in errors with permissions or leaking sensitive information.
+
+When you synchronize files, you should avoid transferring the owner and group by setting `owner: false` and `group: false` arguments.
+When you unpack archives with the `ansible.builtin.unarchive` module you should set the `--no-same-owner` option.
+
+This is an opt-in rule.
+You must enable it in your Ansible-lint configuration as follows:
+
+```yaml
+enable_list:
+  - no-same-owner
+```
+
+## Problematic Code
+
+```yaml
+---
+- name: Example playbook
+  hosts: all
+  tasks:
+    - name: Synchronize conf file
+      ansible.posix.synchronize:
+        src: /path/conf.yaml
+        dest: /path/conf.yaml # <- Transfers the owner and group for the file.
+    - name: Extract tarball to path
+      ansible.builtin.unarchive:
+        src: "{{ file }}.tar.gz"
+        dest: /my/path/ # <- Transfers the owner and group for the file.
+```
+
+## Correct Code
+
+```yaml
+---
+- name: Example playbook
+  hosts: all
+  tasks:
+    - name: Synchronize conf file
+      ansible.posix.synchronize:
+        src: /path/conf.yaml
+        dest: /path/conf.yaml
+        owner: false
+        group: false # <- Does not transfer the owner and group for the file.
+    - name: Extract tarball to path
+      ansible.builtin.unarchive:
+        src: "{{ file }}.tar.gz"
+        dest: /my/path/
+        extra_opts:
+          - --no-same-owner # <- Does not transfer the owner and group for the file.
+```
