Thanks Greg for the confirmation.
The reason behind using 1.9 is:
- I need support for Constrained delegation which is available post 1.8
- My libraries are built using VS2005SP1. And i understand krb5-1.10
onwards versions builds only with VS2010. So i will need to install
VS2010 redistributables as my code builds with 2005. I want to avoid
Please let me know your thoughts.
BTW, Do we have any plan to fix this bug in 1.9? If yes expected release
