When you pass the initial Parallels Plesk Panel configuration, the following error occurs:

"Warning: An error occurred during Customer and Business Manager configuration: Execution failed.
Command: billing_update_admin
Details: The following SSO error occurred: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "">
<html xmlns="">
<title>IIS 7.5 Detailed Error - 405.0 - Method Not Allowed</title>
<style type="text/css">
<tr class="alt"><th>Module</th><td>WebDAVModule</td></tr>
<tr class="alt"><th>Handler</th><td>Plesk_Handler_0-572292915</td></tr>
<tr><th>Error Code</th><td>0x00000000</td></tr>


This error occurs because the WebDAV module is activated in IIS and it blocks SSO and Customers and Business Manager configuration.


1. Disable WebDAV in IIS settings for site "sso-site"
2. Run tool repair-integration
"%plesk_bin%\billing-repair-integration" --command=repair-all --idp-url=https://<hostname>:8443
