- The `uniqueIdentifier` attribute is not appropriate and was relying on `objectClass: extensibleObject` as a workaround to allow it. A more appropriate attribute to use instead is `userID` (_short name: `uid`_).
- Removing `extensibleObject` now requires switching the user accounts to use `inetOrgPerson` class (_which inherits from `organizationalPerson`_). which allows the attributes `givenName`, `userID` and `mail` (_also provided via the `PostfixBookMailAccount` class_).
- The LDAP root object now uses `dc` attributes for `example.test` instead of `localhost.localdomain`. This has nothing to do with DMS or LDAP containers networking config, nor the users mail addresses.
- Users are now grouped under the organizational unit of `users` instead of `people`. Purely a naming change out of preference, no functional difference.
The LDAP test ENV has been updated to accommodate the above changes. An additional ENV override was required for SASLAuthd to switch an attribute set for `ldap_filter` in `/etc/saslauthd.conf` from the implicit default of `uniqueIdentifier` (_that we set during startup as an ENV default for fallback_) to the `userID` attribute.
**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`.

* tests: Switch to setup helper and conventions
* tests: Adapt run command to new conventions
- We have two helper methods with implicit `CONTAINER_NAME` reference, which is a bit more DRY and improves readability.
- `wc -l` + `assert_output 1` converted to use helper `_should_output_number_of_lines 1`
- `DOMAIN` var changed from `my-domain.com` to local testing domain `example.test`.
* tests: Refactor `setup_file()`
- Test wide ENV defined at the top
- OpenLDAP build and run logic grouped together. Added notes, network alias and tty not required.
- Extracted out special LDAP Postfix/Dovecot ENV into separate array. LDAP specific provisioning / auth ENV also included, with comments + linebreak to better group related ENV.
- Likewise additional ENV to support test cases has been extracted to a separate array with additional comments for context.
- Those two arrays are expanded back into the main `CUSTOM_SETUP_ARGUMENTS` that configure hostname and network for the DMS container.
* tests: Refactor the LDAP account table query testcase
- Covers 3 accounts to test from LDAP.
- 2 are the same query against users/aliases/groups tables in Postfix, only differing by account queried (and expected as returned result).
- 1 separate test to ensure a difference in config is supported correctly.
- Extracted repeated test logic into a helper method.
- Added additional context in comments about the creation source of these LDAP accounts and their related Postfix config / interaction. Direct reference to special case PR (since `git blame` will be less useful).
* tests: Use iteration for `grep` setting checks
More DRY approach. With a bit more helpful failure context via `assert_output` (_and only grepping the key_). Simpler to grok what's being covered.
* tests: DRY test email delivery
A bit more verbose with the new helper method. `test-email.txt` template is only used by the LDAP test, as is the `sendmail` command.
Helper will take two args to support the testcases, but at a later date should be refactored to be consistent with the `_send_email()` helper (_which presently uses `nc` that is required for plain-text mail/auth, otherwise we'd have used `openssl`, bigger refactor required_).
* tests: Slight revisions and relocating testcases
- Dovecot quota plugin testcase revised to check files exist instead of rely on `ls` failure.
- Moved Postfix quota plugin testcase into prior dovecot testcase for quota plugin check. Better error output by only querying the `smtpd_recipient_restrictions` setting (_which should be the only one configured for the service_).
- Moved the saslauthd and pflogsumm testcases (_no changes beyond revised comments_) above the `ATTENTION` comment, and one testcase below the comment that belonged to that group.
* tests: Simplify openldap `docker build` command
- `--no-cache` was creating a new image on the Docker host each time the test is run. Shouldn't be any need to build without cache.
- No need to use `pushd` + `popd`, can just provide the path context directly, and the `./Dockerfile` is an implicit default thus `-f` not required either.
Additionally removed the old `checking` prefix from testcase names.
* tests: Move LDAP specific config into `test/config/ldap/`
- No changes to any of these config files, just better isolation as not relevant to any other tests.
- Section heading in `setup_file()` added to distinguish the remainder of the function is dedicated to the DMS container setup.
- Comment providing some context about the `mv` to maintainers, this should be done after defaults are initialized but before starting up the container.
* chore: Appease the lint gods
* Apply suggestions from code review
