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.

	Mechanism	Status
	Kerberos	Working (requires Kerberos ticket for host domain)
	X.509 Certificate	Working (requires certificate issued by host's Certificate Authority)
	OpenID	Working but mod_auth_oid can handle only certain OpenIDs, and mod_auth_openid never worked right.
	Google Account	Has been seen to work once (see comments with OpenID)
	Shibboleth	Vaporware; needs permission from Identity Provider; mod_auth_shib works for a different web app on a different site
	LDAP	Working, requires loginID and password
	IMAP	Roundcube normal login page, requires loginID and password
