Bug in LDAP Authentication in Foreman 1.8.1

Hi All,

It look like a bug to me, please advise:

When trying to login to foreman with "LDAP Authentication" it's case
sensitive. Meaning:
In AD my "User logon name (pre-Windows 2000):" name was "Eddiem" it
didn't work for me. Once I changed it to "eddiem" the authentication
started to work. Shouldn't it be not case sensitive?
If it's matter - I'm making the authentication via some security group I’m
member of.
