---------------------------------------

             Summary: Custom Jcifs Properties
                 Key: CONNECTORS-1588
                 URL: https://issues.apache.org/jira/browse/CONNECTORS-1588
             Project: ManifoldCF
          Issue Type: Improvement
          Components: JCIFS connector
    Affects Versions: ManifoldCF 2.12
            Reporter: Cihad Guzel
             Fix For: ManifoldCF 2.13


In some cases, "jcifs" is running slowly. In order to solve this problem, we need to set custom
some properties. 
 
For example; my problem was in my test environment: I have a windows server and an ubuntu
server in same network in AWS EC2 Service. The windows server has Active Directory service,
DNS Server and shared folder while the ubuntu server has some instance such as manifoldcf,
an db instance and solr. 
 
If the DNS settings are not defined on the ubuntu server, jcifs runs slowly. Because the default
resolver order is set as 'LMHOSTS,DNS,WINS'. It means[1]; firstly "jcifs" checks '/etc/hosts'
files for linux/unix server'', then it checks the DNS server. In my opinion, the linux server
doesn't recognize the DNS server and threads are waiting for every file for access to read.
 
I suppose, WINS is used when accessing hosts on different subnets. So, I have set "jcifs.resolveOrder
= WINS" and my problem has been FIXED. 
 
Another suggestion for similar problem from [another example|[https://stackoverflow.com/a/18837754]]:
"-Djcifs.resolveOrder = DNS"
 
We need to set custom resolveOrder variable.
