Subject RE: MIT Kerberos compatibility
Date Thu, 04 May 2017 12:55:27 GMT
Hi Marc,
I try to run your test(through applying your patch in the trunk) , I think it's success now.
 Could you take some time to check about it?
Here is the log:

Hi Marc,

In case you're not aware of this, please check out the latest fix made by Jiajia. We thought
your case may be different, but would be good to have a check before we can repeat/fix your
case. Thanks.

Kai

Hi Kai,

The terminal output below is for the latest MIT Kerberos 1.15.1 (locally built on Ubuntu Xenial).
Before that, I also tested with the default Xenial MIT Kerberos packages (1.13.2), with the
same result. I did not try earlier MIT Kerberos versions.
