NT sends empty username to 3.0a21

Hi,

I have samba 3.0a21 running and NT 4.0 WS clients.
All workstations were previously in Samba 2.2 domain , so now I upgraded to samba 3.0a22 and
just changed domain name (workstation = XXX) and rejoined workstations by changing domain name
in every WS.

To look at the log it seems like NT WS sends empty username?

*** ldapsam_search_one_user: searching for:[(&(uid=)(objectclass=sambaAccount))]
*** check_password:  Authentication for user [] -> [] FAILED with error NT_STATUS_NO_SUCH_USER

Joining the domain is OK.
Also when I log into WS locally and them map some share with my username/pwd it works OK.
But logging in with same username fails.

Most bizarre thing is that I was testing samba30a21+ldap+pam_ldap+nss_ldap last week in my home
and NT 4.0 WS logging worked.. So probably it's not samba fault. But I'm completly out of ideas,
anyone can help?

P.S. I put level 10 log in the end, hoping that helps..
