> The {{TokenLoginModule}} and specifically TokenProviderImpl [only look at 
> SimpleCredentials.getUserID()|https://github.com/apache/jackrabbit-oak/blob/1144914c053ec9c2723450261fabfee1bd9d0e58/oak-core/src/main/java/org/apache/jackrabbit/oak/security/authentication/token/TokenProviderImpl.java#L165]
>  when creating a token.
> However, in certain situations, such as with the ExternalLoginModule and 
> non-username/password credentials, the SimpleCredentials are used but don't 
> have a user id as the real user id is determined not by the caller of 
> {{Repository.login()}}, but by the external identity provider inside the 
> ExternalLoginModule (and the credentials might not include any kind of user 
> id, say an opaque token from an external service). In this case, 
> {{SimpleCredentials.getUserID()}} returns null and the token implementation 
> fails to create a token and does not return it in the {{.token}} attribute of 
> the credentials.
> Instead, the TokenLoginModule should look at the shared 
> {{javax.security.auth.login.name}} attribute, which can de-facto override a 
> {{SimpleCredentials.getUserID()}}, as it happens in the ExternalLoginModule.
