Details:
Hi,
during a test I ran into a dead lock.
I started 1.500 clients doing kerberos authentication and the server emitted
messages like:
User authentication failed; Seckrb5: Unable to authenticate credentials;;
Request is a replay (p=host/<removed>@CERN.CH)
After this all 1024 threads were locked up waiting for the kerberos
authentication mutex.
