Hi Rob,, I have exact same issue like you described. Also, I have noticed that if I execute same procedure (which goes and fetches data from another linked sql server making this a double hop) using Microsoft JDBC driver procedure executes without a problem - and if I execute the same thing now using JTDS driver, it will also work, but will stop working after ~30 minutes. I have checked Microsoft JDBC driver code and they also set 'credentials delegation' to true: https://github.com/Microsoft/mssql-jdbc/blob/dev/src/main/java/com/microsoft/sqlserver/jdbc/KerbAuthentication.java#L123...
