3.2 Allowing all except specified hosts ('Blacklist')

There are three ways to specify which OpenID hosts (i.e. websites or IP addresses) your users can log in to using their CrowdID:

No restriction — your CrowdID users can log in to any OpenID host
Blacklist — your CrowdID users can log in to any OpenID host except the one(s) that you specify
Whitelist — your CrowdID users can log in to only those OpenID host(s) that you specify

To specify an OpenID blacklist,

Login to CrowdID.
Click the 'Administration' link in the top navigation bar.
Click the 'Trust Relationships' link in the left navigation column.
For 'Restriction Type', select 'Blacklist'.
Wait for a section titled 'Blacklist mode: hosts that can not login' to appear on the screen.
For each site to which you want to prevent users logging in,
1. Type the URL or IP address in the 'Address' field.
2. 「追加」ボタンをクリックします。
