RBPM_Driver_Install Fails error: 'A Schema Update is Required'

During the install of User Application (RBPM) 3.7 and 4.0 running the RBPM_Driver_Install fails with an error "A Schema Update is Required".

This error typically indicates the NrfCaseUpdate utility which modify the schema for attributes "nrfLocalizedDescrs" and
"nrfLocalizedNames" changing the Syntax from "Case Exact String" to "Case Ignore String" for these attributes has not been run or error changing the Syntax. 

To resolve, this issue please do the following:

1. Verify nrfLocalizedDescrs and nrfLocalizedNames attributes Syntax = Case Ignore String   Using iManager > Roles and Tasks > Schema > Attributte Information > find nrfLocalizedDescrs and
nrfLocalizedNames attributes > View and verify Syntax=Case Ignore String.

Fix:
1a. If the syntax is still Case Exact String re-run the NrfCaseUpdate utility or use the command line /root/idm/jre/bin/java -jar NrfCaseUpdate.jar -v
1b. Check the Syntax, this must be o "Case Ignore String" before attempting any other steps below.
1c. Rerun the  RBPM_Driver_Install, if fails then goto steps below
 
2.Check if the default eDirectory ports 389 and 636 have been changed to different ports.  User App 3.7 require eDirectory to be using the default 389 and 635 ports to check the schema.
