Separate username and password lookup
auth.plain_separate module implements authentication using username:password pairs but can use zero or more "table modules" (maddy-tables(5)) and one or more authentication providers to verify credentials.
auth.plain_separate {
user ...
user ...
...
pass ...
pass ...
...
}
How it works: - Initial username input is normalized using PRECIS UsernameCaseMapped profile. - Each table specified with the 'user' directive looked up using normalized username. If match is not found in any table, authentication fails. - Each authentication provider specified with the 'pass' directive is tried. If authentication with all providers fails - an error is returned.
Configuration directives
user table-module
Configuration block for any module from maddy-tables(5) can be used here.
Example:
user file /etc/maddy/allowed_users
pass auth-provider
Configuration block for any auth. provider module can be used here, even 'plain_split' itself.
The used auth. provider must provide username:password pair-based authentication.
