Subject: [PATCH 1/3] sdap_idamp: Fall back to another method if sid is wrong
sss_idmap_domain_has_algorithmic_mapping can return also
IDMAP_SID_UNKNOWN, but it does not mean that idmaping is
unavailable. We should fall back to another method of detection
(sss_idmap_domain_by_name_has_algorithmic_mapping)
and do not return false immediately.

Subject: [PATCH 2/3] LDAP: Don't fail if subdomain cannot be found by sid
Domain needn't contain sid if id_provider is ldap.
With enabled id mapping, user couldn't be stored, because domain
couldn't be found by sid.

Subject: [PATCH 3/3] MAN: Describe change in id mapping with ldap provider
ID mapping could be configured with id_provider ldap only with
enabling option ldap_id_mapping. This behaviour was changed
in the commit d3e1d88ce7de3216a862b
"LDAP: Require ID numbers when ID mapping is off"
ldap_idmap_default_domain_sid need to be also configured since that change.
