Subject: [PATCH 01/21] gp: Support more global trust directories
In addition to the SUSE global trust directory, add support for RHEL and
Debian-based distributions (including Ubuntu).
To determine the correct directory to use, we iterate over the variants
and stop at the first which is a directory.
In case none is found, fallback to the first option which will produce a
warning as it did previously.

Subject: [PATCH 05/21] gp: Convert CA certificates to base64
I don't know whether this applies universally, but in our case the
contents of `es['cACertificate'][0]` are binary, so cleanly converting
to a string fails with the following:
'utf-8' codec can't decode byte 0x82 in position 1: invalid start byte
We found a fix to be encoding the certificate to base64 when
constructing the CA list.
Section 4.4.5.2 of MS-CAESO also suggests that the content of
`cACertificate` is binary (OCTET string).

Subject: [PATCH 11/21] gpo: Test certificate policy without NDES
As of 8231eaf856b, the NDES feature is no longer required on Windows, as
cert auto-enroll can use the certificate from the LDAP request.
However, 157335ee93e changed the implementation to convert the LDAP
certificate to base64 due to it failing to cleanly convert to a string.
Because of insufficient test coverage I missed handling the part where
NDES is disabled or not reachable and the LDAP certificate was imported.
The call to load_der_x509_certificate now fails with an error because it
expects binary data, yet it receives a base64 encoded string.
This adds a test to confirm the issue.

Subject: [PATCH 12/21] gpo: Decode base64 root cert before importing
The reasoning behind this is described in the previous commit message,
but essentially this should either be wrapped in certificate blocks and
imported as PEM, or converted back to binary and imported as DER.
I've opted for the latter since it's how it used to work before it
regressed in 157335ee93e.

Subject: [PATCH 13/21] gpo: Do not get templates list on first run
This is a visual fix and has no impact on functionality apart from
cleaner log messages.
The point of this is to get the list of supported templates in order to
compute a diff between the current applied templates and the updated
list, so we are able to unapply and reapply the policy in case there are
differences.
However this code path is executed on first applies as well, at which
point the root CA is not yet set up. This causes the
`get_supported_templates` call to fail, which is not a hard failure but
still pollutes the logs. In this case it's safe to avoid executing the
command as the policy will be applied regardless.
