In order to provide access to resources that use https, your EZproxy server must be configured with an SSL certificate.

Kortext supports two EZproxy authentication methods: IP authentication and Single Sign-On (SSO). Use the stanza that matches the authentication method configured by Kortext. Kortext provides the URL to proxy, including the providerId, loginSource, and returnUrl parameters. Contact Kortext for the URL configured for your institution.

 Caution: Do not proxy app.kortext.com. EZproxy proxies the initial request to read.kortext.com; after authentication, Kortext redirects the user to app.kortext.com to access the resource directly.

IP Authentication

Title Kortext IP (updated 20261006)
URL https://read.kortext.com/api/identity/v1/ezproxy/callback
HJ read.kortext.com
HJ https://read.kortext.com
NeverProxy app.kortext.com

 Note: Contact Kortext to obtain the URL to use in this stanza.

(for example, https://read.kortext.com/api/identity/v1/ezproxy/callback?providerId=XXXX&loginSource=&returnUrl=)

The URL provided by Kortext includes the providerId and a returnUrl that points to the app.kortext.com URL for the item. EZproxy proxies the initial request to Kortext; after authorization, the user is redirected directly to the app.kortext.com URL.

Single Sign-On (SSO)

Title Kortext SSO (updated 20261006) 
URL https://read.kortext.com/api/identity/v1/ezproxy/callback 
HJ read.kortext.com

AddUserHeader

Replace the URL with the URL provided by Kortext.

SSO requirements

  • Place the Kortext SSO stanza above any ExcludeIP directives in config.txt.
  • The username passed by EZproxy must currently be in email address format.
  • Use the IP and SSO stanzas separately. The SSO AddUserHeader configuration can interfere with IP authentication.
