*Hi all,*
*
*
*I am trying to setup a one-way cross realm trust between a MIT KDC and an
active directory server and up to now I did not success.*
*I hope someone in this list will be able to help me.*
*
*
*My config is as follows:*
* - hadoop version: 0.23.1 with security enable (kerberos).*
* - hadoop realm (mitkdc): HADOOP.REALM*
* - 1 linux node (mitkdc.hadoop.realm - 192.168.198.254) running : hdfs
namenode, hdfs datanode, mit kdc*
* - 1 windows node (ad.domain.realm - 192.168.198.253) running: active
directory 2003*
* - AD realm: DOMAIN.REALM*
*
*
*Everything works well with kerberos enabled if I only use the linux
machine with users having principal in the mitkdc: ivan@HADOOP.REALM*
*
*
*What I am trying to do is to use the user database in the Active directory
(users with principals like ivan@DOMAIN.REALM)*
*
*
*To do that, I setup a one-way cross realm as explained here:
https://ccp.cloudera.com/display/CDH4DOC/Integrating+Hadoop+Security+with+Active+Directory
*
*
*
*From the linux machine I can authenticate against an active directory user
with the kinit command but when I perform a query using the hadoop command
I have the following error message:*

------------------------
*There is no error in the kerberos protocol so i am a little bit lost. If
someone has successfully configured this cross-realm AD/KDC or have any
idea about the problem above, it would be great.*
