Roundcube Mail Single Sign-On

Roundcube Mail normally checks your authentication by obtaining a loginID and password, and trying to use them to authenticate (as you) to the IMAP server. If you have another credential you may specify it here. If you normally use a particular type of credential you may bookmark these links, to bypass this page.
