Obtaining Kerberos tickets via TCP leads to endless loop
--------------------------------------------------------
Key: DIRSERVER-1636
URL: https://issues.apache.org/jira/browse/DIRSERVER-1636
Project: Directory ApacheDS
Issue Type: Bug
Reporter: Stefan Seelmann
Priority: Critical
Fix For: 2.0.0-M2
When obtaining Kerberos tickets via *TCP* the server runs into an endless loop.
The while loop in
org.apache.directory.server.kerberos.protocol.KerberosDecoder.decode() never
terminates.
To reproduce I added a new test class "KerberosTcpITest" in kerberos-test
module, just remove the @Ignore.
Here is the stack:
Thread [NioProcessor-5] (Suspended (breakpoint at line 106 in KerberosDecoder))
KerberosDecoder.decode(IoSession, IoBuffer, ProtocolDecoderOutput)
