Update check go major version way

the previous one just keep one prefix number as the major number, it should be the whole number after the dot.

saml: add tests case covering tampered NameID field (comment)

As sketched here:

https://developer.okta.com/blog/2018/02/27/a-breakdown-of-the-new-saml-authentication-bypass-vulnerability

Thought it was interesting to see how our SAML connector behaved. And
it seems to be behaving well. :)

Update slapd.sh

Before, you could not POST your credentials to a password-connector's
endpoint without GETing that endpoint first. While this makes sense for
browser clients; automated interactions with Dex don't need to look at
the password form to fill it in.

A symptom of that missing GET was that the POST succeeded (!) with

    login successful: connector "", username="admin", email="admin@example.com", groups=[]

Note the connector "". A subsequent call to finalizeLogin would then
fail with

    connector with ID "" not found: failed to get connector object from storage: not found

Now, the connector ID of an auth request will be updated for both GETs
and POSTs.
