Local authentication ignores Accept-Language

[tsujiguchitky]

Description

The SAML2 authentication module has a mechanism to internally call the authentication chain in order to map IdP users to SP users. This authentication chain is called linking authentication chain or local authentication.

The local authentication ignores Accept-Language header. It seems to use the default locale.

Steps to reproduce

1. Start configuration of OpenAM. At that time, set "en_US" as Platform Locale.
2. Configure OpenAM as a SAML SP. At that time, disable auto federation to use local authentication.
3. Change the URL of Assertion Consumer Service (Consumer-> AuthConsumer).
4. Exchange SAML metadata with IdP
5. Configure the SAML2 authentication module. At that time, Linking Authentication Chain is set to ldapService.
6. Set the locale of the browser to Japanese.
7. Try SAML2 authentication and Authenticate on IdP.
8. Check locale when the data store authentication screen is displayed

Expected Results

Local authentication screen is displayed in Japanese.

Actual Results

Local authentication screen is displayed in English.
