Unable to import a Certificate Authority certificate in ArcGIS Server Administrator Directory

Description

Importing a Certificate Authority (CA) certificate returns the following error in ArcGIS Server Administrator Directory:

"Importing CA certificate failed"

Cause

The following are possible causes for the error.

• A different certificate format used.
• An installed root certificate is disallowing the new certificate to be imported.
• Unable to import CA certificate using Microsoft Certificate Manager tool (certmgr.msc).
• An incorrect site binding of Host Name and Port.

Solution or Workaround

The following are possible solutions for the error.

• Use the file format, PKCS#12, to store certificates and associated private key. The extension for this file format is .p12 or .pfx.
• Remove the currently installed root certificate before importing the new CA signed certificate. The following documentation describes this in detail, Configure HTTPs using a new CA-signed certificate.
• Generate and import the .pfx file using Internet Information Services (IIS) Manager.

1. Create a .pfx file to be imported in ArcGIS for Server. The following documentation describes this in detail how to generate the PFX file, Microsoft TechNet: Creating the Personal Information Exchange (PFX) Certificate.
2. Import the newly generated .pfx file in ArcGIS for Server. The following documentation describes this in detail, Configuring HTTPs using an existing certificate.

• Confirm site binding of Host Name and Port are correct. The following documentation describes this in detail, Enable SSL on your web server.
