Searching for a User - Wrong User

I am using LDAP to get my users in RC. When I search for a user it does not even get me close to who I am looking for. I have used full names, usernames, emails, and it does not given me the person I want. It gives me crazy results.

Say I am searching for Sam Smith, username Smiths, email

When I go into search and search any info got Sam Smith it gives me John Apple.

Any Ideas why?

Still cannot figure out why they are coming up with wrong people.
