I don't know what the MIT ssl stores there, but here's my data with Google openid and Stanford shib:

openid:
```
{"first_name": "Jason", "last_name": "Bau", "nickname": null, "email": "jbau@edx.org"}
```

shib:
```
{"REMOTE_USER": "jbau@stanford.edu", "eppn": "jbau@stanford.edu", "Shib-Identity-Provider": "https://idp.stanford.edu/", "sn": "bau", "mail": "jbau@stanford.edu", "givenName": "jason"}
```

in other words, it's nothing that's not already stored with a normal registration.
