Clang-Format doesn't indent template functions in header files - clang-format

Question

I'm having this problem with clang-format not properly indenting my header files. For example, I have a template function in a class and I would expect it to be formatted like so:
template <class T>
class Thing {
public:
T function() {
stuff();
return T;
}
}
I feel like this indentation would happen automatically, however, it doesn't. When I run Clang-format, my function code is indented like this:
template <class T>
class Thing {
public:
T function() {
stuff();
return T;
}
}
How do I get the code in my header files to be formatted like the top one, and not the bottom one?
Below is my .clang-format file:

I opened your config file in this online clang format generator and looked for settings which would be applicable for your example code.
How does this look ?
BasedOnStyle: LLVM
AccessModifierOffset: '-2'
AllowShortFunctionsOnASingleLine: Inline
BreakBeforeBraces: Custom
BreakConstructorInitializers: AfterColon
ColumnLimit: '80'
ConstructorInitializerIndentWidth: '4'
ContinuationIndentWidth: '2'
IndentWidth: '2'
Language: Cpp
NamespaceIndentation: All
PenaltyBreakBeforeFirstCallParameter: '0'
PenaltyBreakComment: '2000'
PenaltyBreakFirstLessLess: '1000'
PenaltyBreakString: '3000'
PenaltyExcessCharacter: '100000'
PenaltyReturnTypeOnItsOwnLine: '10000'
PointerAlignment: Left
SpaceBeforeParens: ControlStatements
Standard: Cpp11
UseTab: Never
I think maybe the UseTab: Never or AccessModifierOffset: '-2' are the relevant settings. There seems to alos be a relation between IndentWidth: and AccessModifierOffset when the later is bigger than the former indentations get messed up.
If these are not the settings you are looking for zed0 is a easy resource to work with for creating an clang format file one can live with.
