Identity Manager Driver Groupwise REST driver fails with "Failed to authenticate GroupWise Admin Service"

When starting the Groupwise REST driver it fails with:

<nds dtdversion="2.0" ndsversion="8.x">
  <source>
    <product build="20150211_0629" instance="GW2014" version="4.0.0.1">DirXML Driver for GroupWise</product>

    <status code="com.novell.gw.dirxml.driver.rest.exceptions.AuthenticationException: Failed to authenticate GroupWise Admin Service" level="fatal" type="app-authentication">

Changing the Driver to connect to use the proper sever name configured for the mta solved the problem.

To verify connectivity use curl:

curl -k -X GET -H "Content-Type: application/json" -H 'Accept: application/json' --user admin https://server:9710/gwadmin-service/system/whoami

Successful result:

{
  "roles" : [ "ROLE_SUPER_ADMIN", "ROLE_ADMIN", "SYSTEM_RECORD" ],
  "user" : {
    "name" : "admin"
  }
}


Failed result:

{"httpStatusCode":401,"statusCode":null,"statusMsg":"Unable to find Admin Service: server:9710","error":true,"params":null,"httpStatus":"UNAUTHORIZED"}

The reason for this is that admin-service will listen on the ip address or dns name configured in:

a) .mta file in domain directory (--ip setting - default blank)
b) mta settings on the mta object

The .mta file will overwrite the setting on the mta.
