Ignore case in Account collector mapping

Hi,

In my account collector, i did not check the "Data is case senesitive" chekbox.

But i have some orphans accounts not mapped cause, it has some uppercase letters in its names

select count(*) from PV_ORPHANED_ACCOUNT, PV_USERS where lower(PV_ORPHANED_ACCOUNT.NAME)=lower(PV_USERS.ADMIN_USER_NAME) or lower(PV_ORPHANED_ACCOUNT.NAME)=lower(PV_USERS.USER_NAME).

that query return 392 orphan account.

Note: in PV_USERS all columns are in lowercase.

I want know, how can i ignore case in the account mapping?

Regards.
