Comment 1 Stef Walter 2013-05-06 11:50:53 UTC
This should be fixed by git commit '00e99ec714bba89c2c484fd90c12de600b7c0de0' in adcli.

Comment 2 Stef Walter 2013-05-06 12:15:48 UTC
There's a use-after-free memory corruption issue that causes adcli to write out invalid memory to its own temporary custom krb5.conf file.
