SAML user binding using email

Binding SAML user identity using email is an good way but insecure way.
Because a user at an connected IDP could if open go in and change email address and then become another user. It would be good to increase security to add a secondary field that will hold the unique Id for a user and this is populated when the user login for the first time to look down the account. And when this field is found this is only used to connecting the user.
And when doing the SAML setup only require a secondary field UniqueID

    When using SAML, you are passing your entire authentication to the 3rd party SAML service. If this IdP is compromized, you cant expect this to be resolved by Domino. So when setting up a trust relationship you have to decide which SAML IdP to trust.

    PS: Which attribute will be used in the SAML assertion is already configurable. Email is just a common method, but you can use your own.
