Missing a User access in the log-on picture

Lacks a user access to log on picture after start-up in Yosemite. In user administration there has been created two user entries - an administrator and a normal access. The normal access is not visible from the log on picture, and it is only possible to access through the visible user (Adm.) and then switch the user by switching in the upper right corner!!!

Wish, possible for all users to log on from the boot up image. (Adm - Normal - Guest access)
