when assigning different templates that add items to the same application, if the Application name's case is not respected.

In Example, if I was to link a template that defines Application "os" (lowercase) to a host that already had the "OS" (uppercase) application, we get the following error message:

Error in query [INSERT INTO applications (name,hostid,applicationid) VALUES ('os','10106','597') ] [Duplicate entry '10106-os' for key 'applications_2']
SQL statement execution has failed "INSERT INTO applications (name,hostid,applicationid) VALUES ('os','10106','597') ".

If I was to change the template to use uppercase "OS" instead, I would not get the error message, and the template would be succesfully linked.

I think this is mostly a standardization issue: Either Applications are case-sensitive and allow for same-name applications with different "case" to co-exist (Application, APPLICATION, application), or they are case-insensitive, and as such should be
mapped" to the current Application name, even if "case" is different (Application, APPLICATION, application --> Application).
