Here are some notes for Jan because I did some things differently than
we agreed on during review:
1.) I chose not to rename 'usercertificate' to 'usercertificate;binary'
and back in pre/post callbacks. Despite the fact that the correct way to
name the certificate attribute is 'usercertificate;binary', I feel that
suddenly renaming it in the new code is asking for trouble.
New code is new, there is no renaming, there is naming, and that naming
should follow standards, and the standard is userCertificate;binary.
(For the record I did not ask for any renaming in *old* host and service
OK I will then use 'usercertificate;binary' and try to not break things.
That would be great, but I'm not sure if there is time for it. Maybe we
can create a ticket for tracking?
I'm all for changing the mapping between CLI options and actual
attribute names but it should be done in a systematic fashion.
+1, shall I post a patch?
2.) I have kept the `normalize_certs` function. It has the potential to
catch incorrectly formatted/encoded certificates and in a way
circumvents the slightly demented way the framework deals with
supposedly binary data.
One sentence above you asked for doing things in systematic fashion.
This is exactly what it isn't. A systematic solution would be a new
parameter type for certificates.
Ha I didn't notice that incorrect encoding is caught by validator.
But I think that we still need to catch malformed certificates that can
not be decoded to DER and AFAIK we don't do that anywhere (failing tests
when adding a random Base64-encoded string confirm this).
All this probably stems from my confusion about the way IPA framework
guesses binary data. For example, if I call `api.Command.user_add_cert`
and fill 'certificate' option with Base64 blob reencoded to Unicode,
everything works as expected.
However, filling this option with 'str' leads to another round of Base64
encoding in the framework, leading to 'userCertificate;binary' which is
filled by original Base64 blob instead of DER encoded cert.
I have also added two negative test cases which deal with incorrectly
encoded and formatted certificates.
