How do you set the username (APP_USER) as the email from single-sign on in APEX?

问题

I'm setting up an APEX app using single-sign on following this tutorial and the app now allows sign-in to occur. However the value of APP_USER does not equal the email address that is logged in through Microsoft - it defaults to APEX_PUBLIC_USER. I want to use the username to provide role-based application access control.

I've looked around for solutions and found post authentication code that looks like it should help and I have tried to adapt.

Using

procedure post_authenticate
is
begin
    w14_auth_pkh.post_authenticate(
        p_username => :APP_USER);
end post_authenticate

or

apex_custom_auth.set_user (p_user => :APP_USER);

I get the following error messages when applying changes from within the authenticate scheme section:

ORA-06550: line 8, column 1: PLS-00103: Encountered the symbol "BEGIN" when expecting one of the following: ; The symbol ";" was substituted for "BEGIN" to continue.

or

ORA-06550: line 2, column 17: PLS-00103: Encountered the symbol "." when expecting one of the following: constant exception table columns long double ref char time timestamp interval date binary national character nchar The symbol "" was substituted for "." to continue.

You first code sample uses a package of Dimitri's, and is missing a semi-colon at the end.

Your relevant code would be APEX_CUSTOM_AUTH.SET_USER();

Alternatively, you could change the Username attribute to something that has been made available via the user info endpoint URL.
