#2723 Could not resolve AD user from root domain

Closed: Fixed None Opened 3 years ago by lslebodn.

There are more administrator users: id administrator @child1.sssdad.com and id administrator @sssdad.com.

sssd is joined to the child domain.

[sssd]
config_file_version = 2
services = nss, pam
domains = child1.sssdad.com

[nss]
default_shell = /bin/bash

[domain/child1.sssdad.com]
debug_level = 0xFFF0

ad_domain = child1.sssdad.com
cache_credentials = True
krb5_store_password_if_offline = True
use_fully_qualified_names = True
fallback_homedir = /home/%d/%u

but user from root domain administrator @sssdad.com cannot be resolved.
It might be cause by fact that user is stored in different domain

It worked for me on sssd-1.13.0. So I "git bisect" it. the first problematic commit is b9e74a7

    LDAP: Add the wildcard_limit option

    Related:
        https://fedorahosted.org/sssd/ticket/2553

    Adds a new wildcard_limit option that is set by default to 1000 (one
    page). This option limits the number of entries that can by default be
    returned by a wildcard search.
