Kerberos interoperability issues

Paul B. Hill, Massachusetts Institute of Technology


MIT's computing environment is a heterogeneous environment that has used Kerberos as a primary authentication method for over a decade. Instead of migrating our existing KDCs to Windows 2000 we have chosen to use cross realm trust to support our Windows 2000 computing environment. During our deployment project we have encountered some interoperability problems and have worked with Microsoft to resolve these. We have also encountered protocol extensions that have been used by Microsoft and we have been working with Microsoft under the umbrella of the IETF to have these documented. Some of the problems were only identified and resolved by analyzing network traffic.
