Error: "Contact your administrator"

Problem

User is unable to log in and receives the error Contact your administrator.

Cause

When integrating with AD FS, the Omnissa Access signing certificate URL was specified as a URL or as XML information.

When AD FS is configured with the Omnissa Access signing certificate URL, the XML file is downloaded for every user login request. If the XML download fails once, this blocks further login attempts and breaks the IDP integration.

Solution

  1. Download the Omnissa Access signing certificate XML file, and copy and paste the content directly into the appropriate AD FS certificate page.
