* chore: Use white-space in query filters to improve readability
* tests: LDAP ENV query filters documented
- These filters remain roughly the same as they were before. The conditions are the same, but restructured to make the complimentary constraints more separated from the actual target attribtues.
- The DOMAIN query additionally includes the `mailAlias` from `PostfixBookMailAccount` class as well.
- Heavy inline documentation breaking down how the filters work for any maintainer to reference. This will likely be migrated after revision into our user docs for LDAP. Some quirks have also been noted with advice for future changes.
* tests: LDAP - Support test-case specific containers
A bit more complicated than other test files due to the larger ENV config array that most containers may need to share.
Example introduced with the test-case checking custom config file support.
* tests: Adjust LDAP test configs
- Paths for `.ldif` files used with volumes shortened
- Postfix LDAP `.cf` files adjusted to conventions used in LDAP tests.
**TL;DR:**
- New image is actively maintained vs existing one that is over 5 years old.
- Slight improvement to LDAP tree config via `.ldif` files.
- No more `Dockerfile` required to build, we can just rely on `docker run`.
`osixia/openldap` has not seen any activity since Feb 2021, while our `Dockerfile` was fixed to v1.1.6` (Feb 2018).
Startup time for this new image is around 5 seconds? (_The LDAP test uses a standard 20 second timeout check to wait until the server is ready before continuing with starting the DMS image_).
This commit migrates to `bitnami/openldap` which required modifying the `01_mail-tree.ldif` to also include adding the root object to start successfully. This image is actively maintained and one of the most popular OpenLDAP images on DockerHub.
The user account `.ldif` files have minimal changes:
- Lines moved around for better organization
- Additional comments for context
- Removal of inherited `objectClass` attributes (`person`, `top`) from the `orgnizationalPerson` class. Attribute `sn` changed to long form `surname` and values corrected with `givenName`. `changetype: add` was also not necessary.
Additionally the image does not support the `.schema` format, they must be converted to `.ldif` which has been done for `postfix-book.schema`.
