Service Desk login does NOT respect use of custom Seraph Authenticator

We use a custom Seraph authenticator / Seraph config to authenticate users against an external Single Sign On process to log in to our JIRA instance.

Standard pages within JIRA (e.g., browsing to a specific issue) correctly respect the Seraph config and redirect unauthenticated users according to the Seraph login.url¹ parameter.

Service Desk does not respect this parameter, and instead, prompts unauthenticated users to log in via it's own custom login page (e.g., <server>/servicedesk/customer/portal/1/user/login).

This is problematic for us. Our users who land on the Service Desk provided login page are stuck; their accounts in JIRA do not have passwords set up, so they can never successfully login on this page.


Steps to reproduce expected behavior:

1. Configure JIRA to use a seraph-config.xml Seraph configuration that includes a value for the login.url parameter.
2. Be logged OUT of JIRA.
3. Browse to a secure page not provided by Service Desk, e.g., <server>/browse/DESK-2.
4. Notice that JIRA redirects you to the login page provided in the Seraph configuration

Steps to reproduce wrong behavior:

1. Configure JIRA to use a seraph-config.xml Seraph configuration that includes a value for the login.url parameter.
2. Be logged OUT of JIRA.
3. Browse to a secure page provided by Service Desk, e.g., <server>/servicedesk/customer/portal/1/DESK-2.
4. Notice that JIRA does not redirect you to the login page provided in the Seraph configuration


Attached, please find three screenshots:

• A snippet of our seraph-config.xml file
• Network activity when starting un-authenticated, going to a "standard" JIRA page, and having JIRA redirect the user according to the Seraph configuration
• Network activity when starting un-authenticated, going to a Service Desk provided page, and having JIRA (wrongly) redirect the user – not to the Seraph specified location – but to a custom Service Desk login page
