It should be compatible, but I have to admit I didn't test it.

There's two ways in which a lookup script can fail: one is if it exits with a
non-zero exit code, and the other is if it makes no output on stdout. Anything
which comes out stderr is put into the autofs log output. So, to test your
script, make sure you're getting the output on stdout ("auto_test args 2>
/dev/null" should show only your expected output), and make sure the exit status
is OK ("auto_test args ; echo $?" should show 0).
