Thanks for providing the updated version. Unfortunately there are still various
problems left, see the comments below.
Patches should have a subject like "component: title". In this case something
like "secur32/tests: Add some tests for lsa functions." might be appropriate.

It is preferred to add tests to existing files. You can still add your own
copyright of course. Splitting in separate files is usually done when there
are sufficient tests.

There is no need to add a separate function for each testcase. Its better to group
them, for example all tests for LsaConnectUntrusted in one function, and so on.

There are still some lines (see for example above) with trailing whitespace in your patch.

You should try to avoid leaks and always close handles at the end of each test - in
this case with LsaDeregisterLogonProcess().

Please always try to document where you observed which status value. Depending on what you
consider more correct, you could mark the other value as broken() and a comment which Windows
versions are affected.

You should remove the & here. Also, you might want to check the result of each function,
even if they are also tested separately.

You might also want to test the auth_package output parameter here.

This triggers a compiler warning here:
lsa.c:90:25: error: assignment discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]
package_name.Buffer = "this is probably not a valid authentication package name";
> + package_name.Length = (USHORT)strlen(package_name.Buffer);
The explicit cast to USHORT should not be necessary here.

Similar to above, the & is wrong here.

You do not really need a separate variable just to pass 0 to a function.
> + protocol_return_buffer, return_buffer_length, protocol_status
Those are supposed to be output pointers (&buffer, ...). Passing NULL is
probably also fine, but no need for separate variables then.

If you use memory allocations, please also free them at the end of the function.
Also, please note that it is usually preferred to use HeapAlloc(), unless the API
requires to use a very specific one.
In this case (fixed size struct) you could also consider allocating the memory
directly on the stack.

You are using tabs here, but the file seems to use spaces.
