After MGNLLDAP-117, LDAP users which logs in Magnolia through MagnoliaRoleResolver or MagnoliaGroupResolver needs an exact match between LDAP and Magnolia username (case sensitive).

Steps to reproduce

1. Create an user at LDAP server with upperCase (e.g, myTestUser)
2. Create an user at Magnolia's Security App matching the username in the step 1 but at lowerCase (e.g, mytestuser).
3. Assign a group to him like travel-demo-editors
4. At your ldap.properties file, set as groupResolverClass 
   Unknown macro: {{info.magnolia.jaas.sp.ldap.resolver.MagnoliaGroupResolver}

   }

5. Restart server to apply ldap file changes
6. Try to login using mytestuser 
7. Check the login doesn't succeed

Expected results
LDAP users logins without any case sensitive restriction

Actual results
LDAP and Magnolia username must match
