SAP Trial - Choose your identity provider - Cannot access trial sap hana database instance

Hello Everyone,

after registering a trial account, I tried to access SAP Hana instance.

I got an error during "Choose your identity provider" (screenshot 1), when selecting "Sign in with the default identity provider".

I put my P-User login informations (I haven't got any S-User login information after trial activation), but I always get this error "Sorry, we could not authenticate you. Try again." (screenshot 2)

Could help me understand where could be the problem or which login information is expected?

Please note I already tried the following solutions:

1) changing the password

2) using email + password couple

3) using p-user + password couple

Thanks in advance

Regards

Francesco
