Make sure the name of the LDAP Server you create in the Groupwise Administrator for the driver, matches the treename of the tree for the server the Groupwise Driver is running on.

Per the Groupwise 2014 REST Driver Documentation:

3.1.5 Associating Identity Vault with GroupWise System
2 a.  Name: Specify the name of your Identity Vault (eDirectory tree).

The name of your LDAP Server you create in the Groupwise Administration tool, must match the name of your tree.

The name the LDAP Server in the Groupwise Administration tool was T-IDM-VAULT11.
The treename was:  VAULT

Hence they do not match thus generating a 404 file not found error because it cannot find the LDAP Server in Groupwise for the driver.
