Public bug reported:
After upgrading sssd from the 12.04 to the quantal version,
1.9.0~beta6-0ubuntu1, sssd no longer works properly.
0. In sssd.conf I have two domains configured, named 'LOCAL' and 'SAMBA'
where the latter uses a Samba 4 beta2 AD LDAP server.
1. While "getent passwd" lists all expected users from passwd and LDAP,
"getent passwd <username>" produces no output and "id <username" results
in "id: <username>: No such user", etc.
2. Running sssd interactively ("sssd -i -d 0xffff") and trying "id foo"
for user "foo" in the LDAP directory produces some interesting debugging
output.
=== BEGIN ===

name 'foo' matched without domain, user is foo

15:20:10 2012) [sssd[nss]] [sss_dp_issue_request] (0x0020): The request has
disappeared?
=== END ===
3. "getent passwd <username>@LDAP" *does* produce output (where
<username> is in the LDAP directory).
4. sssd works properly again if, in the [domain/LOCAL] section of
sssd.conf the line
id_provider = local
is replaced by the line
domain_type = local
Then the debugging output looks like the following

=== END ===
The need to replace 'id_provider' by 'domain_type' is not documented
anywhere I've seen.
