Xwiki ldap use CN and ignore UID_attr

Hello! i have some issue with ldap settings.
i try configure my xwiki.cfg from official guid (i can’t past link here)

but it doesn’t work. So then i enable debug log from off page ((i can’t past link here)

In my log i see how work ldap authentication (and it’s work)

if i use cn of my domain - it work, but i want use sAMAccountName for login. After add UID_attr i was restart tomcat8 and see re initialization xwiki (it means config file was reread i guess)

Ldap server - WinServ with AD (i use it for many services and haven’t problem)

Xwiki.cfg
#-# The authentication management class.

xwiki.authentication.authclass=org.xwiki.contrib.ldap.XWikiLDAPAuthServiceImpl
xwiki.authentication.ldap = 1
xwiki.authentication.ldap.trylocal = 1

xwiki.authentication.ldap.server=.local..com
xwiki.authentication.ldap.port=389
xwiki.authentication.ldap.base_DN=dc=local,dc=***,dc=com
xwiki.authentication.ldap.UID_attr=sAMAccountName
xwiki.authentication.ldap.bind_DN={0}
xwiki.authentication.ldap.bind_pass={1}

xwiki.authentication.ldap.update_user=1
