I have had the same exact problem for about a month or so w/no resolution. RT 3.4.5, mysql (4.1.19 & 5.0.22), fastcgi, apache 2.0.54. As a workaround I switched to Apache auth rather than rt's cookie-based auth. --- Chris Covington IT Plus One Health Management 75 Maiden Lane Suite 801 NY, NY 10038 646-312-6269 http://www.plusoneactive.com
