I cannot mark the correct line in this file but there is a @END tag missing around line 446

@fisx I see also that in this file there is a space missing between @SF.Channel and @TSFI.RESTfulAPI in the lines before:

• "rejects saml responses with invalid issuer entity id"
• "rejects saml responses signed with the wrong private key"
• "rejects saml responses to requests not in cassandra:spar.authreq"
• "rejects saml responses already seen (and recorded in cassandra:spar.authresp)"

Additionally please change @SF.CHANNEL into @SF.Channel
