The option to store credentials is not visible when adding secured services in Portal for ArcGIS

Description

Credentials for services used in Portal for ArcGIS can be stored to enable future usage without having to log in each time the map is opened. However, there are certain cases where the option to store credentials is not visible and the credentials for the services cannot be stored.

Cause

• The services are secured with web-tier authentication, for example, Integrated Windows Authentication (IWA). This is by default.
• The services are inaccessible by Portal for ArcGIS. This may occur if the service is blocked by a firewall, or the services proxy is not configured correctly.
• The SSL certificate used by the service is not trusted by Portal for ArcGIS.

Solution or Workaround

Depending on the cause, the workarounds provided are applicable.

• Disable the firewall on the web service. For more information, refer to Microsoft Support: Turn Windows Firewall on or off.
• Configure the services proxy on Portal for ArcGIS. For more information, refer to How To: Configure a forward proxy server with Portal for ArcGIS 10.2.2.
• Configure Portal for ArcGIS to trust the provided SSL certificates. For more information, refer to Portal for ArcGIS: Configuring the portal to trust certificates from your certifying authority.
