Samba: user share without 2nd authentication request

Hello together,

iam setting up samba4 with openwrt like described in the openwrt samba wiki.
i'am using samba in "user share" mode. i have setup a share and a user (smbpasswd -a newuser). the user is the same username and password like on the windows-client .

when i access the share from the windows client windows asks for username and password. i can access the share when i make the authentication. but i'am already authenticated beacause i logged in into windows. i dont want to type in username/password a second time.

here is the log

[2022/09/12 19:59:41.916266,  1] ../../source3/smbd/service.c:354(create_connection_session_info)
  create_connection_session_info: guest user (from session setup) not permitted to access this share (ssd)

many thanks for hints for solving this problem
