No upper case characters allowed in group-names

For better readability the group names should be allowed Upper-case characters. From within LDAP it really does not matter. I have groups with upper case letters up and running fine.

How to reproduce:

• Log in to FD and navigate to "Groups and Roles"
• Try to add or modify a group and set the name to contain some upper-case characters (e.g. "Linux-Login" for users allowed to login to linux)
• when saving or applying you get this message: "The field 'Name' contains invalid characters. 'LS' are not allowed!"
