add a query_state parameter to several auth functions that execute
internal queries. currently the queries use the
internal_distributed_query_state() query state, and we maintain this as
default, but we want also to be able to pass a query state from the
caller.
in particular, the auth queries currently use a timeout of 5 seconds,
and we will want to set a different timeout when executed in some
different context.
ldap_role_manager depends on standard_role_manager,
therefore it needs to wait for superuser initialization.
If this is missing, the password authenticator will start
checking the default password too early and may fail to
create the default password if there is no default
role yet.
Currently password authenticator will create password
together with the role in such case but in following
commits we want to separate those responsibilities correctly.
This PR extends authentication with 2 mechanisms:
- a new role_manager subclass, which allows managing users via
LDAP server,
- a new authenticator, which delegates plaintext authentication
to a running saslauthd daemon.
The features have been ported from the enterprise repository
with their test.py tests and the documentation as part of
changing license to source available.
