Section-based auth config #3446

chrzaszcz · 2021-12-10T16:36:28Z

Change the way auth methods are specified:

Sections for each auth method are now required.
A list of auth methods is no longer required. It can be used to enable selected methods in a specific order. When not specified, it is created automatically from the auth method sections in alphabetical order.

Motivation:

Check for required options was broken - when a method was on the list but there was no section for it (no options configured), the check did not work.
Defaults could not be introduced without having all sections always enabled, which would clutter the configuration.

Other changes:

Moved the check for unsupported auth methods and modules to the TOML processing. This way it is easier to test and more consistent. The tests are changed to have less mocking and to be consistent with the rest of the suite and the check for error patterns can now be used in other test cases as well.

Planned in the next PR:

Defaults for the auth methods.
Moving scram_iterations to auth.password.

Example 1 - before:

[auth]
  methods = ["ldap"]

  [auth.ldap]
    base = "ou=Users,dc=esl,dc=com"
    filter = "(objectClass=inetOrgPerson)"

After - the auth section itself can be skipped as it has no options:

[auth.ldap]
  base = "ou=Users,dc=esl,dc=com
  filter = "(objectClass=inetOrgPerson)"

Example 2 - before:

[auth]
  methods = ["rdbms"]
  scram_iterations = 64

After - the subsection is now necessary:

[auth]
  scram_iterations = 64
  [auth.rdbms]

Alternatively:

[auth]
  scram_iterations = 64
  rdbms = {}

Example 3 - most complicated, unlikely:

[auth]
  methods = ["rdbms", "ldap"]

  [auth.ldap]
    base = "ou=Users,dc=esl,dc=com"
    filter = "(objectClass=inetOrgPerson)"

After - rdbms section needs to be added. methods is still needed to sort them.

[auth]
  methods = ["rdbms", "ldap"]

  [auth.ldap]
    base = "ou=Users,dc=esl,dc=com"
    filter = "(objectClass=inetOrgPerson)"

  [auth.rdbms]

Now the auth mthods are declared by including the section(s) instead of listing the methods. The list of methods is optional and used to specify method order. Motivation: - Required method options were enforced only if the relevant section was present, but the section could be omitted even though the method was enabled. - The possibility to specify default values for method options without always including all subsections for unused methods. - Simplicity: in most cases only one method is enabled and the list of methods can be omitted.

Also: - Test auth methods with real names as the mocked modules were invalid. Using real names is easier than mocking helper functions inside mongoose_config_spec. - Test missing modules in a separate simple test case.

Use the callback for the root element for the check. Main motivation is to keep error handling consistent and simplify testing.

Errors are generated the same way for all types of issues, so the same code can be reused. Also: - Module names changed to real ones in the file test - assert_error logic is updated to handle more detailed tests with checking the reason and other attributes

Also: add missing information about the changed host_config.

Looks good to me :) I like how unsupported auth methods and modules are checked now.
