Descripción: The REST API allows Upper case String Values and the REST User Search cannot search for upper case values.

Pasos para repetir:

1.  Log into Blackboard Learn via REST API
2.  Create a user via REST.  Note user created via SIS and GUI will all have the text set to lower case. 
3.  Use POST request to https://clientURL/learn/api/public/v1/users (replace the clientURL for your own URL)

{

"externalId": "J5555",
"dataSourceId": "_2_1",
"userName": "J5555",
"studentId": "J5555",
"educationLevel": "Unknown",
"gender": "Unknown",
"password": "1234",
"name":

{ "given": "andy ", "family": "hulme", "middle": "george", "preferredDisplayName": "GivenName" }

}

Observed Behavior:

"externalId": "J5555",

Use the search

https://clientURL/learn/api/public/v1/users/?externalId=J5555 (replace the clientURL for your own URL)

Empty Array

A direct call will show the information correctly:

https://clientURL/learn/api/public/v1/users/externalId:J5555  (replace the clientURL for your own URL)

Expected Behavior:

The search should either be case-insensitive, REST should set all external Id’s to lower case.

Note: The user "J5555" is not mandatory, it was used just as an example.
