Feel free to file an RFE..although in the case you are trying to
solve,
it wouldn't help you anyway and I'm not sure if it's useful in
general.
The ldap_access_filter is anded with a "base filter" inside the SSSD,
which looks something like this, depending on your schema:
(cn=$username)(objectclass=posixUser)
Then the SSSD performs a search with the complete filter and allows
access only if the search yields a single result.
In your specific case, the complete filter would look something like
this:
(&((cn=$username)(objectclass=posixUser)(&(cn=sysadmins)(memberuid=$USER))))
Which wouldn't do what you seem to want, i.e. only allow members of
the
sysadmins group.
Unfortunately if you're using the RFC2307 schema, there is no simple
way
to create a filter that would point to a specific group.

Providers cannot be stacked, sorry, there can only be one provider in
a
domain.
You can, however, define two domains that point to the same servers
and
differ by the access provider value only.
sorry if this has been discused before, i just landed in sssd world.
why don't make simple_allow_users|groups an option of any provider?
i know some providers have their own filtering mechanism but it makes more sense to me
having a global allow|deny_users|groups option.
