#### Nested groups usage in LDAP/AD
If you are using Active directory with nested groups you have to add LDAP_MATCHING_RULE_IN_CHAIN: :1.2.840.113556.1.4.1941: to your query.
For example:
```shell
group_search_filter: (&(objectClass=group)(member:1.2.840.113556.1.4.1941:=%d))
user_dn_search_filter: (&(memberOf:1.2.840.113556.1.4.1941:=CN=group,DC=dc,DC=net)(sAMAccountName=%s))
```

### Sample settings

		"lookup_bind_password=admin",
		"user_dn_search_base_dn=dc=min,dc=io",
		"user_dn_search_filter=(uid=%s)",
		"user_dn_attributes=sshPublicKey",
		"group_search_base_dn=ou=swengg,dc=min,dc=io",
		"group_search_filter=(&(objectclass=groupofnames)(member=%d))",
	}
	_, err := s.adm.SetConfigKV(ctx, strings.Join(configCmds, " "))
	if err != nil {
		c.Fatalf("unable to setup LDAP for tests: %v", err)
	}

		LDAPUserDNSearchFilter: globalIAMSys.LDAPConfig.LDAP.UserDNSearchFilter,
		LDAPGroupSearchBase:    globalIAMSys.LDAPConfig.LDAP.GroupSearchBaseDistName,
		LDAPGroupSearchFilter:  globalIAMSys.LDAPConfig.LDAP.GroupSearchFilter,
	}
	s.OpenID = globalIAMSys.OpenIDConfig.GetSettings()
	if s.OpenID.Enabled {
		s.OpenID.Region = globalSite.Region()
	}
	return s
}
