ibm mobilefirst - IBM Worklight 5.0.5 - Realm is not defined in authenticationConfig.xml -

here error receive our websphere application server liberty profile running worklight server:

defaultoptions:onfailure procedure invocation error. runtime: realm 'singlestepauthrealm' not defined in authenticationconfig.xml.

this runs fine on local server.

i have rebuilt , deployed server customization war file server, , restarted it.

could because version of remote server not match version of local server? local server version is: 5.0.5.20121129-1027

here authenticationconfig.xml:

update:

thanks orlando's answer, able discern server versions:
server version: 5.0.5.20121130-0919
local version: 5.0.5.20121129-1027

the version (probably build number, not sure how wl versions work) different; however, suspect minor version mismatch not issue.

here have tried far debug issue:

1. i followed steps in worklight documentation build , upload server customization file proper directory on server.

   you can find steps in ic article under heading "deploying project".

2. i opened war file , noticed authenticationconfig.xml not in there! so, figured manually push xml same folder resides in on local server. in case,this directory is: /opt/ibm/worklight/server/wlp/usr/servers/worklightserver/worklight.home/app_name/conf

3. i figured might have been permissions issue, set +rwx on file. still no dice.

4. maybe looking other files in directory on local server? uploaded of them , tried permissions again. no luck.

5. i restarted server after each 1 of these steps (and in case of step 4, restarted twice, once default perms , once full perms).

have tried suggestion in question?

basically:

how many .war files have deployed in application server?
in worklight 5 there can 1. make sure case.
