Kerberos on Wall Street

Isaac Hollander, P. Rajaram, and Constantin Tanno
Morgan Stanley & Co. Incorporated
New York, NY


Morgan Stanley, an international financial services firm, has a significant investment in Kerberos. We have been using Kerberos 4 since 1993, and began a transition to Kerberos 5 in 1995. Kerberos has helped us progress towards solving the classic security problems of cleartext passwords and single sign-on. However, because of Morgan Stanley's specialized requirements, and a lack of support for Kerberos among operating system and application vendors, we have faced a number of practical integration problems not faced by the research community. This paper discusses those problems, the tools we have built to solve them, and the areas in which we feel vendors must provide better support for Kerberos.
