Integration client machines with LDAP might require lot of firewall tickets, which can be a pain especially when users keep on adding new client machines. When the client is not integrated with LDAP for the group mapping, NFS should not use the group list in the request. Instead, NFS gateway can get the group list from local name service. This JIRA is to track the effort to provide a configuration option to get list of GID from LDAP/OS for making the deployment at Cloud easier. Also this can remove the limitation of 15 GID in the NFS request. -- This message was sent by Atlassian JIRA (v6.2#6252)

Prior to JDK 6, we can check if a string is empty in 2 ways:
* if(s != null && s.length() == 0)
* if(("").equals(s)) or if( s.equals(""))
Starting from JDK 6, String class has a new convenience and efficient method
isEmpty() to check string's length.
