We're trying to use the Rally excel add-in v2.4.4 and using Broadcom OKTA SSO IDP URL we were not able to login - Possible 404 error.
Release : SAAS
Component : AGILE CENTRAL
Rally follows the SAML specification for SSO authentication. This specification requires a value called the RelayState=RelayState=noRedirect to be passed among the participants for an OKTA SSO authentication handshake.
1. Open Excel.
2. Click on Rally Tyle.
3. Click - connect to CA Agile central
4. Change the Basic authentication to SSO
5. In Rally's internal environment we use a URL parameter named TargetResource to set the RelayState so the URL should be
https://CustomerACS?fromURI=/app/broadcomincexternal_rally_1/exk1gdbaindeR1Jrj1d8/sso/saml&RelayState=noRedirect
Eg: For 3019 use https://avagoext.okta.com/sso/saml2/0oa1gl4zrimfru9lx1d8?fromURI=/app/broadcomincexternal_rally_1/exk1gdbaindeR1Jrj1d8/sso/saml&RelayState=noRedirect
6. To know your ACS URL please contact your internal Rally administrator or Rally support if you are having trouble constructing a URL.
