var/check_mk/wato/auth/auth.php is a file generated dynamically by Checkmk at runtime to handle NagVis Multisite Authorization. It was previously also present as an empty placeholder in the OMD site skeleton.

Because the file content is generated dynamically, it never matched the empty skeleton version, causing omd diff to report a spurious modification on every fresh or updated site. This was confusing and made it harder to detect actual configuration drift.

The empty skeleton file has been removed and auth.php is now excluded from omd diff tracking, consistent with other dynamically generated files. The file itself continues to be generated and used as before — this change only affects how omd diff reports it.
