I have checked with our people working on cas servers and the authentication works fine, but it seems that there is an issue with the redirect. Before I had the entire website behind a login with wordpress login enabled (just in case). This time I made several pages public and disabled the wordpress login. When trying to visit the private pages, the user automatically get our cas login page (which is fine). According to our server logs the user gets authenticated, but the user receives this error in browser: ERR_TOO_MANY_REDIRECTS (error code comes from Chrome). Do you know what the cause is for too many redirects? Our cas server version is 4.2.2
