Hi,
I have a few questions:
1. Is the `bin/shield/esusers` script executable?
2. Did you verify that the environment variable was set properly before installing Shield? You can check with `echo $ES_JAVA_OPTS`
3. Does the user you ran `bin/shield/esusers` with have write permission on the `/etc/elasticsearch` directory?

Environment path echo $ES\_JAVA\_OPTS
-Des.path.conf=/etc/elasticsearch
Then , esusers are executable only , when i try to execute i got an error
./esusers

It looks like the Shield script is having issues finding the necessary classes. Does the /usr/share/elasticsearch/lib/elasticsearch-\*.jar file exist?

Ok, the version of elasticsearch is probably the issue. Shield only works with Elasticsearch 1.4.2+ and I'd recommend moving to Elasticsearch 1.6 with Shield 1.3.
If you must use an older version of Elasticsearch, then Shield 1.1 is compatible with Elasticsearch 1.4.x.

Are you using this plugin [https://github.com/couchbaselabs/elasticsearch-transport-couchbase](https://github.com/couchbaselabs/elasticsearch-transport-couchbase) ? If so, then take a look at their readme, it describes the versions of elasticsearch that it is compatible with.
Also, Shield is not compatible with Elasticsearch 1.3.
