Ignore case when NexusIQ authenticaes with LDAP

as per implementation of nexusIQ at our end, we use different authentication for http and https request.
For http: nexusIQ talk with ldap configured using csgloginIDshort and from there user able to login to portal.
For https: we have Kerberos reverse proxy authentication enabled which takes csgLoginId of user and authenticates with ldap at the end.
For some regions we have seen csgLoginId and csgloginIDshort differs in cases and hence nexus complains about ldap authentication and time out in the end.

Can NexusIQ set optional flag to ignore lower/upper case difference so both users can be treated as same and not different by Nexus.
